I'm trying to use the Google Search API on my Android App and I have added the documents in the index.
Now I'm retrieving the document by its ID and I want to update just some fields, not all of then.
That I tried to do but with no success:
// Fetch a single document by its doc_id
Document doc = index.get(myDocID);
LOG.warning("FOUND DOC " + doc.toString());
doc.newBuilder()
.addField(Field.newBuilder()
.setName("field1")
.setNumber(valueForField1))
.addField(Field.newBuilder()
.setName("field2")
.setNumber(valueForField2))
.addField(Field.newBuilder()
.setName("field3")
.setDate(valueForField3))
.build();
LOG.warning("NEW DOC " + doc.toString());
try {
index.put(doc);
LOG.warning("PUT OK");
} catch (PutException e) {
if (StatusCode.TRANSIENT_ERROR.equals(e.getOperationResult().getCode())) {
// retry putting the document
}
LOG.warning("ERROR");
}
In the code above I'm trying to update just 3 fields of my document.
The only info that I found in the documentation is that if I want to Reindex a document I have to save a new one with the same ID and it will be Reindexed.
Do I have to fill all the fields or there's a way to update just some fields?
I appreciate any answers
You need to copy all properties (fields, facets, doc_id, etc.) of the existing document to the new builder. Document.newBuilder is static and is not using any of the existing document's data.

I need to create various reports in PDF format and email it to specific person. I managed to load HTML template into string and am replacing certain "custom markers" with real data. At the end I have a fulle viewable HTML file. This file must now be printed into PDF format which I am able todo after following this link : https://www.appcoda.com/pdf-generation-ios/. My problem is that I do not understand how to determine the number of pages from the HTML file as the pdf renderer requires creating page-by-page.
I know this is an old thread, I would like to leave this answer here. I also used the same tutorial you've mention and here's what I did to make multiple pages. Just modify the drawPDFUsingPrintPageRenderer method like this:
func drawPDFUsingPrintPageRenderer(printPageRenderer: UIPrintPageRenderer) -> NSData! {
let data = NSMutableData()
UIGraphicsBeginPDFContextToData(data, CGRect.zero, nil)
printPageRenderer.prepare(forDrawingPages: NSMakeRange(0, printPageRenderer.numberOfPages))
let bounds = UIGraphicsGetPDFContextBounds()
for i in 0...(printPageRenderer.numberOfPages - 1) {
UIGraphicsBeginPDFPage()
printPageRenderer.drawPage(at: i, in: bounds)
}
UIGraphicsEndPDFContext()
return data
}
In your custom PrintPageRenderer you can access the numberOfPages to have the total count of the pages
Problem: I routinely receive PDF reports and annotate (highlight etc.) some of them. I had the bad habit of saving the annotated PDFs together with the non-annotated PDFs. I now have hundreds of PDF files in the same folder, some annotated and some not. Is there a way to check every PDF file for annotations and copy only the annotated ones to a new folder?
Thanks a lot!
I'm on Win 7 64bit, I have Adobe Acrobat XI installed and I'm able to do some beginner coding in Python and Javascript
Please ignore the following suggestion, since the answers already solved the problem.
EDIT: Following Mr. Wyss' suggestion, I created the following code for Acrobat's Javascript console to be run only once at the beginning:
counter = 1;
// Open a new report
var rep = new Report();
rep.size = 1.2;
rep.color = color.blue;
rep.writeText("Files WITH Annotations");
Then this code should be applied to all PDFs:
this.syncAnnotScan();
annots = this.getAnnots();
path = this.path;
if (annots) {
rep.color = color.black;
rep.writeText(" ");
rep.writeText(counter.toString()+"- "+path);
rep.writeText(" ");
if (counter% 20 == 0) {
rep.breakPage();
}
counter++;
}
And, at last, one code to be run only once at the end:
//Now open the report
var docRep = rep.open("files_with_annots.pdf");
There are two problems with this solution:
1. The "Action Wizard" seems to always apply the same code afresh to each PDF (that means that the "counter" variable, for instance, is meaningless; it will always be = 1. But more importantly, var "rep" will be unassigned when the middle code is run on different PDFs).
2. How can I make the codes that should be run only once run only at the beginning or at the end, instead of running everytime for every single PDF (like it does by default)?
Thank you very much again for your help!
This would be possible using the Action Wizard to put together an action.
The function to determine whether there are annotations in the document would be done in Acrobat JavaScript. Roughly, the core function would look like this:
this.syncAnnotScan() ; // updates all annots
var myAnnots = this.getAnnots() ;
if (myAnnots != null) {
// do something if there are annots
} else {
// do something if there are no annots
}
And that should get you there.
I am not completely positive, but I think there is also a Preflight check which tells you whether there are annotations in the document. If so, you would create a Preflight droplet, which would sort out the annotated and not annotated documents.
Mr. Wyss is right, here's a step-by-step guide:
In Acrobat XI Pro, go to the 'Tools' panel on the right side
Click on the 'Action Wizard' tab (you must first make it visible, though)
Click on 'Create New Action...', choose 'More tools' > 'Execute Javascript' and add it to right-hand pane > click on 'Execute Javascript' > 'Specify Settings' (uncheck 'prompt user' if you want) > paste this code:
.
this.syncAnnotScan();
var annots = this.getAnnots();
var fname = this.documentFileName;
fname = fname.replace(",", ";");
var errormsg = "";
if (annots) {
try {
this.saveAs({
cPath: "/c/folder/"+fname,
bPromptToOverwrite: false //make this 'true' if you want to be prompted on overwrites
});
} catch(e) {
for (var i in e)
{errormsg+= (i + ": " + e[i]+ " / ");}
app.alert({
cMsg: "Error! Unable to save the file under this name ('"+fname+"'- possibly an unicode string?) See this: "+errormsg,
cTitle: "Damn you Acrobat"
});
}
;}
annots = 0;
Save and run it! All your annotated PDFs will be saved to 'c:\folder' (but only if this folder already exists!)
Be sure to enable first Javascript in 'Edit' > 'Preferences...' > 'Javascript' > 'Enable Acrobat Javascript'.
VERY IMPORTANT: Acrobat's JS has a bug that doesn't allow Docs to be saved with commas (",") in their names (e.g., "Meeting with suppliers, May 11th.pdf" - this will get an error). Therefore, I substitute in the code above all "," for ";".
So I've coded a VSTO addin using vb.net to add a header to a document in Word however from historical methods we have lots of templates with field codes. My addin does not account for these and simply strips the header to add xxxxx value you choose from the pop up.
I need my code to be smart enough to 'spot' the field code and append or if it does not exist e.g. a blank document then continue running as expected. I can append this field code using the below code:
wordDocument.Variables("fieldname").Value = "xxxx"
wordDocument.Fields.Update
However my tool then adds the header as normal and strips most the content from the template. So effectively my question is how would I code a check for this before proceeding. So in plain English I would need my addin to go from this:
Load pop up
Set xxxx value in header
Close
To this:
Load pop up
Check Document for existing "fieldname"
If "fieldname" exists then
wordDocument.Variables("fieldname").Value = "xxxx" (from pop up selection)
wordDocument.Fields.Update
However if "fieldname" doesn't exist then continue as normal....
Sorry if this is a little complex and/or long winded.
Thanks in advance.
Here is my code in C#, hope this might help you to code in VB.Net
foreach (Section sec in doc.Sections)
{
doc.ActiveWindow.View.set_SeekView(WdSeekView.wdSeekCurrentPageHeader);
foreach (HeaderFooter headerFooter in sec.GetHeadersFooters())
{
doc.ActiveWindow.View.set_SeekView(headerFooter.IsHeader ? WdSeekView.wdSeekCurrentPageHeader : WdSeekView.wdSeekCurrentPageFooter);
if (headerFooter.Range.Fields.Count > 0)
{
//Append to existing fields
UpdateFields(headerFooter.Range.Fields);
}
else
{
//Add field code
AddFieldCode(headerFooter.Range);
}
}
doc.ActiveWindow.View.set_SeekView(WdSeekView.wdSeekMainDocument);
}
Extension method to iterate through the header types
public static IEnumerable<HeaderFooter> GetHeadersFooters(this Section section)
{
List<HeaderFooter> headerFooterlist = new List<HeaderFooter>
{
section.Headers[WdHeaderFooterIndex.wdHeaderFooterPrimary],
section.Headers[WdHeaderFooterIndex.wdHeaderFooterFirstPage],
section.Headers[WdHeaderFooterIndex.wdHeaderFooterEvenPages],
section.Footers[WdHeaderFooterIndex.wdHeaderFooterPrimary],
section.Footers[WdHeaderFooterIndex.wdHeaderFooterFirstPage],
section.Footers[WdHeaderFooterIndex.wdHeaderFooterEvenPages]
};
return headerFooterlist;
}
I am currently evaluating iTextSharp for potential use in a project. The code that I have written to achieve my goal is making use of PDFCopy.GetImportedPage to copy all of the pages from an existing PDF. What I want to know is what all do I need to be aware of that will be lost from a PDF and/or page when duplicating PDF content like this? For example, one thing that I already noticed is that I need to manually add in any bookmarks and named destinations into my new PDF.
Here's some rough sample code:
using (PdfReader reader = new PdfReader(inputFilename))
{
using (MemoryStream ms = new MemoryStream())
{
using (Document document = new Document())
{
using (PdfCopy copy = new PdfCopy(document, ms))
{
document.Open();
int n;
n = reader.NumberOfPages;
for (int page = 0; page < n; )
{
copy.AddPage(copy.GetImportedPage(reader, ++page));
}
// add content and make further modifications here
}
}
// write the content to disk
}
}
Basically anything that's document-level instead of page-level will get lost and both Bookmarks and Destinations are document-level. Pull up the PDF spec and look at section 3.6.1 for other entries in the document catalog including Threads, Open and Additional Actions and Meta Data.
You might already have seen these but here are some samples (in Java) of how to merge Named Destinations and how to merge Bookmarks.
BACKGROUND
I have a java program that analyzes data and creates a pdf report using itext 5.
I recently had to add a summary of major problems at the start of the document so a user would not have to read over a hundred pages to find problems. Problems are only discovered when serially looking through the data.
I solved the problem by creating 3 pdf documents and then merging them, a start/title pdf, the summary of problems pdf, and the body or analysis pdf. (Basically splitting the original document at the point I wanted to insert the summary)
I use PdfReader and PdfCopy to combine the documents. I am able to keep the chapter bookmarks OK.
THE PROBLEM
As I encounter a significant problem I add it to the 'summary' document. I want to add a link in the summary to point to the problem in the body.
I tried to use Chunk.setLocalDestination and setLocalGoto but realized why that did not work, so I tried using setLocalDestination and setRemoteGoto (with and without 'file://'), but that did not work either. (Also, I used the final pdf document name in the RemoteGoto, not the temporary pdf document name.)
I do not want to use bookmarks because that seems wrong and would not look right.
I am hoping someone could suggest an alternate method or make a suggestion.
To recap, in my current code a create a Chunk with setLocalDestination and that chunk goes into the 'body' document. At the same time I create a setRemoteGoto which is put into the summary document. I was hoping when they were combined the link would work, but when the link is clicked, you go to the first page of the combined document.
Thanks.....
PS I have both iText in action books
CLARIFICATION 3/5/2014
What I was calling 'bookmarks' are really Chapter class entities that are inserted into sections of the 3 documents as they are being created.
After saving the 3 documents, PdfReader is used to open each and PdfCopy is used to put them into a new, final document.
I get the data from the Chapters, which creates the 'bookmarks' on the left side of the Pdf reader used by the user, e.g. Acrobat Reader.
int thisPdfPages = reader.getNumberOfPages();
reader.consolidateNamedDestinations();
java.util.List<HashMap<String, Object>> bookmarks = SimpleBookmark.getBookmark(reader);
if (bookmarks != null) {
if (pageOffset != 0) {
if (debug3) auditLogger.log("Shifting pages by " + pageOffset );
SimpleBookmark.shiftPageNumbers(bookmarks, pageOffset, null);
}
masterBookmarks.addAll(bookmarks);
}
for (int i = 0; i < thisPdfPages;) {
page = copy.getImportedPage(reader, ++i);
stamp = copy.createPageStamp(page);
// add page numbers
ColumnText.showTextAligned(stamp.getUnderContent(), Element.ALIGN_CENTER, new Phrase(String.format("page %d of %d", start + i, totalPages)), 297.5f, 28, 0);
stamp.alterContents();
copy.addPage(page);
}
PRAcroForm form = reader.getAcroForm();
if (form != null) {
copy.copyAcroForm(reader);
}
When analyzing the data I have 2 documents open, a base document which contains all the details and a summary document which contains notable events over some thresholds.
//NOTE section is part of the 'body' document
//NOTE summaryPhrase is a part of the 'summary' document
String linkName = "summaryPf_" + networkid ;
//create Link target
section.add(new Chunk("CHANGE TO EMPTY STRING WHEN WORKING").setLocalDestination( linkName ));
//create Link
Chunk linkChunk = new Chunk( "[Link] " );
Font linkFont = new Font( regularFont );
linkFont.setColor(BaseColor.BLUE);
linkFont.setStyle( Font.UNDERLINE );
linkChunk.setFont( linkFont );
boolean useLocal = true;
// both local and remote goto's fail
if (useLocal) {
linkChunk.setLocalGoto( linkName);
} else {
// all permutations of setting filename fail,
// but it does bring up a permissions dialog when the link is clicked.
//String remotePdfName = "file://./" + pdfReportName ;
//String remotePdfName = "file://" + pdfReportName ;
//String remotePdfName = "file:" + pdfReportName ;
String remotePdfName = pdfReportName ;
linkChunk.setRemoteGoto( remotePdfName, linkName);
}
// add link to summary document
summaryPhrase.add( linkChunk );
summaryPhrase.add( String.format("There were %d devices with ping failures", summaryCount));
summaryPhrase.add( Chunk.NEWLINE );
}
If I use setLocalGoto, when you click the link in the final document you goto the first page.
If I use setRemoteGoto, a dialog ask permission to go to a document, but the document fails to open, tried several permutations on filename.
