Richard, To enable the guarantee you need to specify "spellcheck.maxCollationTries" with a value other than zero (which is default). There is cost involved with verifying beforehand if the collations will return hits so this feature is "off" by default. Also, you may want to enable extended collations with "spellcheck.collateExtendedResults" to know beforehand how many hits you'll get. It also will detail exactly which correction was subbed in for which original misspelled word.
Two things you might want to be aware of: - This is new functionality for 3.1 so it doesn't work on 1.4 without a patch (see SOLR-2010 in jira). - There is a critical bug in the spell check collate functionality that affects any use of "spellcheck.collate=true" in 3.1 and Trunk (4.x). If using collate (even *without* "spellcheck.maxCollationTries") you should apply SOLR-2462 first (see https://issues.apache.org/jira/browse/SOLR-2462 for information & a patch). It is likely this (or a similar fix) will eventually get committed and included in the next bug-fix release, should there be one.

According to the wiki by using spellcheck.collate any fq parameters that are passed through to the original query while doing spellcheck will return results if the collation is re-run. So far this has not been happening. I am getting results returned but if I re-run the query passing through the collated q param it finds nothing. My initial Query i as follows: http://127.0.0.1:8983/solr/select?q=reeed%20bulll&spellcheck=true&spellcheck.collate=true&fq=content_type:post and I get back in the spellcheck lst <lst name="spellcheck"> <lst name="suggestions"> <lst name="reeed"> <int name="numFound">1</int> <int name="startOffset">0</int> <int name="endOffset">5</int> <arr name="suggestion"> <str>red</str> </arr> </lst> <lst name="bulll"> <int name="numFound">1</int> <int name="startOffset">6</int> <int name="endOffset">11</int> <arr name="suggestion"> <str>bull</str> </arr> </lst> <str name="collation">red bull</str> </lst> </lst> The issue is if I run the query again using the 'correct' query http://127.0.0.1:8983/solr/select?q=red%20bull&spellcheck=true&spellcheck.collate=true&fq=content_type:post&wt=json I get no reponses returned. This is because of my content_type:post, which is filtering correctly. I have also run spellcheck.build=true I have set up my solrconfig.xml as follows. <searchComponent name="spellcheck" class="solr.SpellCheckComponent"> <str name="queryAnalyzerFieldType">textgen</str> <lst name="spellchecker"> <str name="classname">solr.IndexBasedSpellChecker</str> <str name="spellcheckIndexDir">./spellchecker</str> <str name="field">name</str> <str name="buildOnCommit">true</str> <str name="spellcheck.collate">true</str> </lst> </searchComponent> <requestHandler name="search" class="solr.SearchHandler" default="true"> <lst name="defaults"> <str name="echoParams">explicit</str> <int name="rows">10</int> </lst> <arr name="last-components"> <str>spellcheck</str> </arr> </requestHandler> My scheme.xml declares textgen fieldsType and name field <field name="name" type="textgen" indexed="true" stored="true"/> <fieldType name="textgen" class="solr.TextField" positionIncrementGap="100"> <analyzer type="index"> <tokenizer class="solr.WhitespaceTokenizerFactory"/> <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" enablePositionIncrements="true" /> <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="0" splitOnCaseChange="0"/> <filter class="solr.LowerCaseFilterFactory"/> </analyzer> <analyzer type="query"> <tokenizer class="solr.WhitespaceTokenizerFactory"/> <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/> <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" enablePositionIncrements="true" /> <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="0" catenateNumbers="0" catenateAll="0" splitOnCaseChange="0"/> <filter class="solr.LowerCaseFilterFactory"/> </analyzer> </fieldType> Thanks Richard -- View this message in context: http://lucene.472066.n3.nabble.com/spellcheck-collate-returning-all-results-tp2975621p2975621.html Sent from the Solr - User mailing list archive at Nabble.com.
