Solr suggester no results - apache

I want to use the Solr suggester component for city names. I have the following settings:
schema.xml
Field definition
<fieldType class="solr.TextField" name="textSuggest" positionIncrementGap="100">
<analyzer>
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.StandardFilterFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
</fieldType>
The field i want to apply the suggester on
<field name="city" type="string" indexed="true" stored="false"/>
The copy field
<copyField source="city" dest="citySuggest"/>
The field
<field name="citySuggest" type="textSuggest" stored="false" indexed="true" />
solr-config.xml
<requestHandler name="/suggest" class="solr.SearchHandler" startup="lazy">
<lst name="defaults">
<str name="suggest">true</str>
<str name="suggest.count">10</str>
<str name="suggest.dictionary">mySuggester</str>
</lst>
<arr name="components">
<str>suggest</str>
</arr>
</requestHandler>
<searchComponent name="suggest" class="solr.SuggestComponent">
<lst name="suggester">
<str name="name">mySuggester</str>
<str name="lookupImpl">FuzzyLookupFactory</str>
<str name="dictionaryImpl">DocumentDictionaryFactory</str>
<str name="field">citySuggest</str>
<str name="suggestAnalyzerFieldType">string</str>
</lst>
</searchComponent>
Then i run
http://localhost:8983/solr/company/suggest?suggest=true&suggest.dictionary=mySuggester&wt=json&suggest.q=Ath&suggest.build=true
to build the suggest component
Finally i run
http://localhost:8983/solr/company/suggest?suggest=true&suggest.dictionary=mySuggester&wt=json&suggest.q=Ath
but i get an empty result set
{"responseHeader":{"status":0,"QTime":0},"suggest":{"mySuggester":{"Ath":{"numFound":0,"suggestions":[]}}}}
Are there any obvious mistakes? Any thoughts?


Τry the following:
In the field with name="citySuggest" set the attribute stored="true".
Then rebuild the suggester.

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?

Solr - Suggester not returning any suggestiions

I'm trying to setup the Solr suggester module.
I've followed the guide and setup my core as such:
solrconfig.xml
<searchComponent class="solr.SpellCheckComponent" name="suggest">
<lst name="spellchecker">
<str name="name">suggest</str>
<str name="classname">org.apache.solr.spelling.suggest.Suggester</str>
<str name="lookupImpl">org.apache.solr.spelling.suggest.tst.TSTLookup</str>
<str name="field">city</str> <!-- the indexed field to derive suggestions from -->
<float name="threshold">0</float>
<str name="buildOnCommit">true</str>
</lst>
</searchComponent>
<requestHandler class="org.apache.solr.handler.component.SearchHandler" name="/suggest">
<lst name="defaults">
<str name="spellcheck">true</str>
<str name="spellcheck.dictionary">suggest</str>
<str name="spellcheck.onlyMorePopular">false</str>
<str name="spellcheck.count">5</str>
<str name="spellcheck.collate">true</str>
</lst>
<arr name="components">
<str>suggest</str>
</arr>
</requestHandler>
schema.xml
<types>
<fieldType class="solr.TextField" name="textSpell" positionIncrementGap="100">
<analyzer>
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.StandardFilterFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
</fieldType>
</types>
<fields>
<!-- my other fieldsfields -->
<field name="city" type="textSpell" indexed="true" stored="true"/>
</fields>
and then rebuild the spellcheck with:
http://localhost:4569/solr/myCore/suggest?q=a&spellcheck=true&spellcheck.build=true
and then do a search:
http://localhost:4569/solr/myCore/suggest?q=aberdean&spellcheck=true&spellcheck=on
but I always get an empty suggestions in the response:
<response>
<lst name="responseHeader">
<int name="status">0</int>
<int name="QTime">1</int>
</lst>
<lst name="spellcheck">
<lst name="suggestions"/>
</lst>
</response>
I've checked the suggestions in this question
Any idea why I'm not getting results?

Can you commit and try your query? I guess it's because of the
<str name="buildOnCommit">true</str>
Can you try again making it false.

Solr 4.0 UI issue

I just discovered today that there is a new solr release (4.0 ALPHA). So, I give it a try. After setting it up (under Tomcat) I had the following error message:
This interface requires that you activate the admin request handlers, add the following configuration to your solrconfig.xml:
<!-- Admin Handlers - This will register all the standard admin RequestHandlers. -->
<requestHandler name="/admin/" class="solr.admin.AdminHandlers" />
The above error popped up when I added the following in the solrconfig.xml:
<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">
<lst name="defaults">
<str name="config">data-config.xml</str>
</lst>
</requestHandler>
Does anybody know what it is wrong?
Thank you in advance,

I checked the log file and i guess the error lies here/ Can't find resource 'solrconfig.xml' in classpath or 'solr.\conf/ It is not able to locate the solrconfig.xml file.
Apology,i dont know how to rectify it. May be a pro can . Cheers :)

This is caused most likely by some other error in your config. To find out what is going on go to Tomcat folder /logs/ and look for a file catalina.*.log
Reading through exception message you should be able to figure out witch part of configuration fails, if not paste it here.

I was having similar a problem when trying to deploy as a webapp under tomcat. I found this tutorial http://adeithzya.wordpress.com/2011/08/25/using-apache-solr-with-spring-framework/ and was able to get admin UI to work with one minor change, ie instead of windows file structure i was using Mac OS.
"I will be using Apache Tomcat as the web server for SOLR, hence browse to Tomcat configuration directory, in my case it’s “C:\apache-tomcat-6.0.32\conf\Catalina\localhost” add new .xml file “my-solr-app.xml” (it can be any name). Here are the content of the .xml file:
Start Apache Tomcat and open a browser to the “http://localhost:8080/my-solr-app/”, you may need to change the port number configured for Tomcat web server. If you see the welcome screen, then you’ve just finished Apache SOLR setup."
I had a small hiccup because i did not copy the correct folder, ensure you copy the entire "example" directory in your new directory

In solr ALPHA 4.0 distribution there is example folders. go to example-->solr--config folder
and copy the solrconfig.xml to your core whatever you have created . and if you r using data import handler copy this in solrconfig.xml
data-config.xml
your problem will be solved i have already tried and succeded

I had this same error. To fix it first make sure tomcat knows where your solr home is.
you can either set the path to solr home in the webapps/solr/web.xml file
<env-entry>
<env-entry-name>solr/home</env-entry-name>
<env-entry-value>/Path/To/My/solr/Home/solr/</env-entry-value>
<env-entry-type>java.lang.String</env-entry-type>
Or you can do this export JAVA_OPTS=”$JAVA_OPTS -Dsolr.solr.home=/my/custom/solr/home/dir/”
I also upgraded to tomcat 7.0.8 because there's a url bug in earlier versions of tomcat 7 that prevent solr from working.

Indexing binary files from database issue (no errors)

I am trying to index binary files stored in a database (mysql) and I have no success. I have a solr configured as below:
Solr file structure
+solr
+bookledger(core0)
-conf
+lib(all necessary libraries)
+contrib
+dist
+data
+bookledger
-index
-spellchecker
+ktimatologio
-index
-spellchecker
+ktimatologio(core1)
-conf
+lib(all necessary libraries)
+contrib
+dist
As you can see the configuration concerns a multicore solr setup. Now, on the bookledger(core0) I have indexed binary files successfully (stored in a database). In the second core when I conduct full-import I see no errors! Then, when I try to query the binary content the output is like: [B#660b1b14. What am I missing here?
Thank you in advance,
Tom

Finally i have found the solution. Notice the entity queries and the column definition in the data-config.xml:
....
<entity name="aitiologikes_ektheseis_bin"
query="select id, title, model, type, url, last_modified, CONCAT_WS('_',id,model) AS solr_id, bin_con AS content from aitiologikes_ektheseis where type = 'bin'"

deltaQuery="select id, title, model, type, url, last_modified, CONCAT_WS('_',id,model) AS solr_id, bin_con AS content from aitiologikes_ektheseis where type = 'bin' and last_modified > '${dataimporter.last_index_time}'"
transformer="TemplateTransformer"
dataSource="db">
<entity dataSource="fieldReader" processor="TikaEntityProcessor" dataField="aitiologikes_ektheseis_bin.content" format="text">
<field column="id" name="id" />
<field column="solr_id" name="solr_id" />
<field column="title" name="title" stripHTML="true" />
<field column="model" name="model" stripHTML="true" />
<field column="type" name="type" stripHTML="true" />
<field column="url" name="url" stripHTML="true" />
<field column="last_modified" name="last_modified" stripHTML="true" />
<field column="content" name="content" stripHTML="true" />
</entity>
</entity>
</document>
</dataConfig>
In order "Tika" to "see" the content and extract it, i have to change the "content" to "text".
One thing more. The correct syntax is:
<entity name="aitiologikes_ektheseis_bin"
query="select id, title, model, type, url, last_modified, CONCAT_WS('_',id,model) AS solr_id, bin_con AS text from aitiologikes_ektheseis where type = 'bin'"
deltaImportQuery="select id, title, model, type, url, last_modified, CONCAT_WS('_',id,model) AS solr_id, bin_con AS text from aitiologikes_ektheseis where type = 'bin' and id='${dataimporter.delta.id}'"
deltaQuery="select id, title, model, type, url, last_modified, CONCAT_WS('_',id,model) AS solr_id, bin_con AS text from aitiologikes_ektheseis where type = 'bin' and last_modified > '${dataimporter.last_index_time}'"
transformer="TemplateTransformer"
dataSource="db">
<field column="id" name="id" />
<field column="solr_id" name="solr_id" />
<field column="title" name="title" />
<field column="model" name="model" />
<field column="type" name="type" />
<field column="url" name="url" />
<field column="last_modified" name="last_modified" />
<entity dataSource="fieldReader" processor="TikaEntityProcessor" dataField="aitiologikes_ektheseis_bin.text" format="text">
<field column="text" name="content" />
</entity>
</entity>
</document>
</dataConfig>
I hope this helps someone.
Be well,
Tom

Solr admin interface analysis results and solr search results do not match

There are 6 indexed document in Solr with the text field "name_texts". The Admin UI highlights field value when it is "blue-cat" and the search term is "blueCat". But the search query returns 0 results. Why that happens ?
http://localhost:8982/solr/select?q=name_texts:blueCat

Admin UI -> Analysis highlights results (screenshot)

I think that your query is not good regarding to your datas !
May I ask you to give a try like this :
- field q --> *:*
- field fq --> nam-texts:*blueCat*
URL
http://localhost:8983/solr/select?q=*%3A*&fq=name_texts%3A*blueCat*&indent=true
Give me some feedback! :)
