How can I get more feature fields from Solr highlight output?
Currently the Highlight just returns the text snippet and docID.
During the indexing step I indexed the feature alongside with other fields I'd like to get back.
Thank you in advance!
You can specify other fields to return highlighting on using the hl.fl parameter. For multiple extra fields, just use that field repeatedly. For example, if you want to highlight in the fields author and title, you would append
&hl.fl=author&hl.fl=title
to your Solr query. Take a look at the linked page for other highlighting options.

I am just getting started with Apache Solr.
I have successfully run through the Apache tutorials and have now created my own collection and indexed my files.
Whilst the documentation is extensive I cannot find if there is a way to query all fields, but only return the fields that the search string/query was found in.
For example, if I have a file:
Filename: Weekly Report For Company X.pdf
Associated / indexed meta-data:
"id":"S:\\Weekly Reports\\JAN\\Weekly Report For Company X.PDF",
"date":["2017-11-02T19:14:07Z"],
"pdf_pdfversion":[1.6],
"company":["Microsoft"],
"access_permission_can_print_degraded":[true],
"subject":["weekly report; reports; weekly"],
"contenttypeid":["0x010100F29081EC69D67544A17D8172A093E42E"],
"dc_format":["application/pdf; version=1.6"],
If I query for "Weekly Report" I only want to return the 'id' and 'subject' fields as these are the only fields that contain the actual queried values. If other fields contained the string, I would want them returned too.
I'm leaning towards 'it cannot be done' (but hope I am wrong) as I liken it to a SQL query. It has to know what fields to return in the SQL statement and does not remove fields based on no matching string.
Since I don't know the matched fields before running the query I cannot use the filter list option at the point of executing the query.
Is this possible?
While this may be not precisely what you want, but you could mimic similar behaviour with highlighting.
All you need to do - is to create dismax query with qf being all fields that you have (e.g qf=id,subject,company)
Then you need to request highlighting, request all fields for it (hl.fl=id,subject,company) and enable hl.requireFieldMatch which would force Solr to return only fields which were matched for the query.
In this case you will have a highlighting section, that will contain ids of the matched documents and only highlighted contents of matched fields
I have a search index and require a lucene query which will conditionally search specified fields. The end result will be that if you're logged into the website, all fields will be searched, or if you're logged out, specified fields will be skipped by modifying the lucene query.
The closest I have at the moment is:
+(term1~ term2~) +_culture:([en-gb TO en-gb] [invariantifieldivaluei TO invariantifieldivaluei]) **-FieldToIgnore1:(term1 term2) -FieldToIgnore2:(term1 term2)**
The problem with this however is if one of the search terms exists in one of the fields not mentioned (FieldToIgnore1 or FieldToIgnore2), then the document is ignored because it's been excluded as one one of the fields to ignore were matched.
How can this be modified so lucene doesn't even match against the fields to ignore?
Instead of qualifying your search via Lucene and the Smart Search Results webpart, have you tried modifying the searchability of the document fields themselves. You can set search parameters on the Page Type or index itself.
Go to Page Types --> [your doc type] --> Search fields, and set what fields are and aren't exposed to searching.
Version 9 gives you these settings in the Smart Search app. See these docs for details.
I'm using sunspot and solr for a rails app to search ebook contens, for highlight feature I have to set the ebook_content as a stored filed, every time I queried solr for result, it sends back the entire document content about the book, which makes the query very slow.
How could I only get the result without the stored field?
The fl parameter of Solr allows you to specify which fields you want returned in the result. If you had fields id, title, ebook_content, then you could use fl=id,title to omit the ebook_content field. I don't think there's support in Solr for getting all fields except one (e.g. -ebook_content).
Update
If you don't want to return the field in the normal results, but still want highlighting on that field, exclude the field as I described above, then turn on the highlighter:
hl=true
set the field(s) which should be highlighted:
hl.fl=ebook_content
and set the size of the highlighting fragment (in characters):
hl.fragsize=50
your finished query looks something like this:
?q=search term&fl=id,title&hl=true&hl.fl=ebook_content&hl.fragsize=50
I'm using a data view to display a list (Sharepoint 2010) that has several columns including one that has a Name column. I've provided the user with a text filter on the page to send values to filter the Name column in this list. The problem I'm facing is that the filter only works for exact matches and not partial matches.
I tried to overcome this problem by using Sharepoint Designer to:
create a parameter that uses the textbox control value.
Filtering the Name column with this parameter and setting the comparison to "Contains"
Unfortunately if the default value of the Parameter is blank, the list does not display any data. If the default value of the parameter is set to part of a name in the list, the list displays names that contain that string. However, when changing the value in the text box and searching, the list does not return results. Please let me know if you guys know how to fix this. Any help is much appreciated and let me know if you need any additional information. Thanks!
Managed to find a solution to my problem. I used a custom javascript solution designed by jvossers (http://instantlistfilter.codeplex.com) that involves the list being filtered instantly much like Google's search!
The only downside of this solution is that it only filters the items currently displayed on the screen. Therefore, if you have a data view web part which limits the amount of items displayed on the page, this solution won't help you. In order to facilitate this solution, display all the row items on the page (by increasing the item limit per page to a larger number than your total list rows) and then add this code into a content editor web part on the same page. Worked brilliantly for me. '
By the way if you are using jQuery 1.3.x or higher, you should modify the script a little as described in the disscussion here: http://instantlistfilter.codeplex.com/Thread/View.aspx?ThreadId=49123
I am running a Solr instance on Jetty and when I search using the Solr admin panel, it returns the entire document. What should I do to get only specified fields from each Solr document returned by the search?
/?q=query&fl=field1,field2,field3
From the Solr Admin home page, click on "Full Interface". On that page there is a box called "Fields to Return". You can list the you want here (comma-separated). "*" means all fields.
http://xx.xxx.xx.xx:8983/solr/corename/select?indent=on&q=*:*&wt=json&fl=ImageID,Imagepath,Category
This link has fl parameter:
fl is a field list, which will display the specified fields from the indexed list.
The best way is to run the query from Admin concole. When we run it, it also provides the actuall SQL query executed. Just copy the query and use it.
About the question: select specific fields from the table. In the admin console look for 'FL' text box. write the field names you want to retrieve, comma sapereted. Hit the 'Execute Query' button.
Top right side the SQL will be available.
Generated Query: ......select?fl=FIELDNAME&indent=on&q=:&wt=json
you can simply pass fl parameter with required fields name in your query.
&fl=field1,field2,field3&query=:
your response documents contains only mentioned fields.
