Solr: Facet is not creating any output - apache

I am using Solr 4.4.0 and running some basic queries. This is what I do when i insert title:* in the query box
<?xml version="1.0" encoding="UTF-8"?>
<response>
<lst name="responseHeader">
<int name="status">0</int>
<int name="QTime">3</int>

and so on and so forth 70 times...
And this is okay, because this is the result I want(70 books), but when I try to add the facet.field = publisher, it doesn't do anything. It returns the exact same output as above. How can I get this facet to work? the indexing is set to true and everything. what am I doing wrong? Here is an excerpt of my schema:
<field name="title" type="text_general" indexed="true" stored="true" multiValued="true"/>
<field name="subject" type="text_general" indexed="true" stored="true"/>
<field name="description" type="text_general" indexed="true" stored="true"/>

<field name="numpages" type="int" indexed="true" stored="true"/>
<field name="isbn" type="text_general" indexed="true" stored="true"/>

You need to change text_general on publisher field which uses WhitespaceTokenizerFactory means it splits phrases/strings into chunks whenever it encounters whitespace.
<field name="publisher" type="text_general" indexed="true" stored="true"/>
So Cambridge University Press is divided into
Cambridge
University
Press
Either remove that tokenizer or use other fieldType which doesn't use WhitespaceTokenizerFactory
You can use string fieldtype so update following and restart Solr and index data again
<field name="publisher" type="string" indexed="true" stored="true"/>

I have followed the apache solr offical documentation but made changes to solr-config.xml according to them still have the same issue.
After reading your question and if I am not wrong, you are posting PDF file (which contains some text and images) to solr. The solr will only index that document it will not extract the images and store them to other location.
Solr internally uses Tika libraries for parsing the documents, but it cannot be used in your requirement
To achieve your requirement,
parse your pdf and extract all the images and other contents and store them
index all the extracted contents and pdf in solr.

Solr - How to make several searches on a single query?

I'm trying to make a query that:
First try to match strings, just lowercase processing, and generate a score, boost x
Second, try to use the 'text_en' processing and generate a score, boost y
Trird, Use 'text_en' with synonyms, and generate a score, boost z
Is this possible?
I made the following configuration but I don't think it's doing what I described... It works but I don't trust on the results.
solrconfig.xml:
<requestHandler name="/querystems" class="solr.SearchHandler">
<lst name="defaults">
<str name="echoParams">explicit</str>
<str name="wt">json</str>
<str name="indent">true</str>
<str name="qf">
lowercase^2 title_without_synonym description_without_synonym title_stems^1.5 description_stems^1
</str>
<str name="q.alt">*:*</str>
<str name="rows">100</str>
<str name="fl">id,title,description,reuseCount,score,title_stems,description_stems</str>
<str name="defType">edismax</str>
</lst>
</requestHandler>
schema.xml:
<field name="title" type="text_en_test" indexed="true" stored="true"/>
<field name="title_without_synonym" type="text_en_without_synonym" indexed="true" stored="true"/>
<field name="title_stems" type="text_en_stems" indexed="true" stored="true"/>
<copyField source="title" dest="title_without_synonym" maxChars="30000" />
<copyField source="title" dest="title_stems" maxChars="30000" />
<field name="description" type="text_en_test" indexed="true" stored="true"/>
<field name="description_without_synonym" type="text_en_without_synonym" indexed="true" stored="true"/>
<field name="description_stems" type="text_en_stems" indexed="true" stored="true"/>
<copyField source="description" dest="description_without_synonym" maxChars="30000" />
<copyField source="description" dest="description_stems" maxChars="30000" />
I don't even know why that 'lowercase' field works at the query configuration, as it's a 'fieldType', not 'field'... Can someone help me undestanding and better configurating this scenario?

index all files inside a folder in solr

I am having troubles indexing a folder in solr
example-data-config.xml:
<dataConfig>
<dataSource type="BinFileDataSource" />
<document>
<entity name="files"
dataSource="null"
rootEntity="false"
processor="FileListEntityProcessor"
baseDir="C:\Temp\" fileName=".*"
recursive="true"
onError="skip">
<field column="fileAbsolutePath" name="id" />
<field column="fileSize" name="size" />
<field column="fileLastModified" name="lastModified" />
<entity
name="documentImport"
processor="TikaEntityProcessor"
url="${files.fileAbsolutePath}"
format="text">
<field column="file" name="fileName"/>
<field column="Author" name="author" meta="true"/>
<field column="text" name="text"/>
</entity>
</entity>
</document>
then I create the schema.xml:
<field name="id" type="string" indexed="true" stored="true" required="true" multiValued="false" />
<field name="fileName" type="string" indexed="true" stored="true" />
<field name="author" type="string" indexed="true" stored="true" />
<field name="title" type="string" indexed="true" stored="true" />
<field name="size" type="plong" indexed="true" stored="true" />
<field name="lastModified" type="pdate" indexed="true" stored="true" />
<field name="text" type="text_general" indexed="true" stored="true" multiValued="true"/>
finally I modify the file solrConfig.xml adding the requesthandler and the dataImportHandler and dataImportHandler-extra jars:
<requestHandler name="/dataimport" class="solr.DataImportHandler">
<lst name="defaults">
<str name="config">example-data-config.xml</str>
</lst>
</requestHandler>
I run it and the result is:
Inside that folder there are like 20.000 files in diferent formats (.py,.java,.wsdl, etc)
Any suggestion will be appreciated. Thanks :)
Check your Solr logs . Answer for what is the Root Cause will definitely be there . I also faced same situation once and found through solr logs that my DataImportHandler was throwing exceptions because of encrypted documents present in the folder . Your reasons may be different, but first analyze your solr logs, execute your entity again in DataImport section, and then check the immediate logs for errors by going on the logging section on admin page . If you are getting errors other than I what I mentioned , post them here , so they can be understood and deciphered .

Solr 4 Lucene - Error loading class 'Solr.UUIDField'

Trying to create a UUID field in my schema.xml, I just get this error when starting Solr:
Plugin init failure for [schema.xml] fieldType "uuid": Error loading class 'Solr.UUIDField'
My schema looks like:
<fields>
<field name="uuid" type="uuid" indexed="true" stored="true" />
<updateRequestProcessorChain name="uuid">
<processor class="solr.UUIDUpdateProcessorFactory">
<str name="fieldName">uuid</str>
</processor>
<processor class="solr.RunUpdateProcessorFactory" />
</updateRequestProcessorChain>
<field name="id" type="string" indexed="true" stored="true" required="true"/>
<field name="address" type="text_general" indexed="true" stored="true"/>
<field name="city" type="text_general" indexed="true" stored="true" />
<field name="county" type="string" indexed="true" stored="true" />
<field name="lat" type="text_general" indexed="true" stored="true" />
<field name="lng" type="text_general" indexed="true" stored="true" termVectors="true" termPositions="true" termOffsets="true" />
<field name="price" type="float" indexed="true" stored="true"/>
<field name="bedrooms" type="float" indexed="true" stored="true" />
<field name="image" type="string" indexed="true" stored="true"/>
<field name="region" type="location_rpt" indexed="true" stored="true" />
<defaultSearchField>address</defaultSearchField>
<field name="_version_" type="long" indexed="true" stored="true"/>
<field name="text" type="text_general" indexed="true" stored="false" multiValued="true"/>
And then in
<fieldType name="uuid" class="Solr.UUIDField" indexed="true" />
From the docs
I'm confused as the the location on the <updateRequestProcessorChain/> section. I feel it shouldn't go in the field declaration part.
The field class is case sensitive probably, try will lower case solr solr.UUIDField :-
<fieldType name="uuid" class="solr.UUIDField" indexed="true" />

Solr 4 - missing required field: uuid

I'm having issues generating a UUID using the dataImportHandler in Solr4. Im trying to import from an existing MySQL database.
My schema.xml contains:
<fields>
<field name="uuid" type="uuid" indexed="true" stored="true" required="true" />
<field name="id" type="string" indexed="true" stored="true" required="true"/>
<field name="address" type="text_general" indexed="true" stored="true"/>
<field name="city" type="text_general" indexed="true" stored="true" />
<field name="county" type="string" indexed="true" stored="true" />
<field name="lat" type="text_general" indexed="true" stored="true" />
<field name="lng" type="text_general" indexed="true" stored="true" termVectors="true" termPositions="true" termOffsets="true" />
<field name="price" type="float" indexed="true" stored="true"/>
<field name="bedrooms" type="float" indexed="true" stored="true" />
<field name="image" type="string" indexed="true" stored="true"/>
<field name="region" type="location_rpt" indexed="true" stored="true" />
<defaultSearchField>address</defaultSearchField>
<field name="_version_" type="long" indexed="true" stored="true"/>
<field name="text" type="text_general" indexed="true" stored="false" multiValued="true"/>
</fields>
<uniqueKey>uuid</uniqueKey>
and then in <types>
<fieldType name="uuid" class="solr.UUIDField" indexed="true" />
My Solrconfig.xml contains:
<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">  
<updateRequestProcessorChain name="uuid">
<processor class="solr.UUIDUpdateProcessorFactory">
<str name="fieldName">uuid</str>
</processor>
<processor class="solr.RunUpdateProcessorFactory" />
</updateRequestProcessorChain>
<lst name="defaults">
<str name="config">data-config.xml</str>
</lst>
Whenever I run the update, some docs are inserted ok , buy many return with:
org.apache.solr.common.SolrException: [doc=204] missing required field: uuid
Going by the example at link it should be
<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">
.........
<lst name="defaults">
<str name="config">data-config.xml</str>
<str name="update.chain">uuid</str>
</lst>
</requestHandler>
<updateRequestProcessorChain name="uuid">
<processor class="solr.UUIDUpdateProcessorFactory">
<str name="fieldName">uuid</str>
</processor>
<processor class="solr.RunUpdateProcessorFactory" />
</updateRequestProcessorChain>
