All, I am trying to apply the spell check in the Solr 5.3.1.
Currently Solr 5.3.1 already includes the SpellCheckComponent. which looks like below .
<searchComponent name="spellcheck" class="solr.SpellCheckComponent">
<str name="queryAnalyzerFieldType">text_general</str>
<lst name="spellchecker">
<str name="name">default</str>
<str name="field">text</str>
<str name="classname">solr.DirectSolrSpellChecker</str>
<str name="distanceMeasure">internal</str>
<float name="accuracy">0.5</float>
<int name="maxEdits">2</int>
<int name="minPrefix">1</int>
<int name="maxInspections">5</int>
<int name="minQueryLength">4</int>
<float name="maxQueryFrequency">0.01</float>
</lst>
<lst name="spellchecker">
<str name="name">wordbreak</str>
<str name="classname">solr.WordBreakSolrSpellChecker</str>
<str name="field">name</str>
<str name="combineWords">true</str>
<str name="breakWords">true</str>
<int name="maxChanges">10</int>
</lst>
</searchComponent>
But When I tried to consume this function. like this.
http://10.2.21.38:7574/solr/gettingstarted_shard1_replica2/spell?q=%E7%94%B2&wt=json&indent=true
I got response with exception said
All checkers need to use the same Analyzer
I also tried to search some solution from the internet. and found some solutions like below .
Solr 4.0 How can I change the spellchecker analysers so they are all the same?
Solr spellcheck: cannot show result, always receiving same error
So I tried to follow the answers to change these fields to the same one.
<str name="field">text</str>
<str name="field">name</str>
to the same field
like this .
...
<str name="field">EntryCNName</str>
....
<str name="field">EntryCNName</str>
which is defined in the schema.
<field name="EntryCNName" type="text_ik" indexed="true" stored="true"/>
the field type definition is
<fieldType name="text_ik" class="solr.TextField">
<analyzer type="index" isMaxWordLength="false" class="org.wltea.analyzer.lucene.IKAnalyzer"/>
<analyzer type="query" isMaxWordLength="true" class="org.wltea.analyzer.lucene.IKAnalyzer"/>
</fieldType>
But unfortunately still got the same error. Could someone please help to figure out what does it mean for this error ? How to fix it ?
Thanks.
Upated
I make something progress.
I found the <str name="field">xx</str> defined in the searchComponent should defined in the schema. and in the requestHandler .the xxx of the <str name="spellcheck.dictionary">xxx</str> should be from the spellchecker name.
for example in my case they are default and wordbreak.
So I change my configuration like below.
Schema.xml
<field name="id" type="string" indexed="true" stored="true" required="true" multiValued="false" />
<field name="_version_" type="long" indexed="true" stored="true"/>
<field name="_root_" type="string" indexed="true" stored="false"/>
<!--<field name="Name" type="string" indexed="true" stored="true"/>-->
<field name="EntityID" type="string" indexed="false" stored="true"/>
<field name="EntryCNName" type="text_ik" indexed="true" stored="true"/>
<field name="EntryEnName" type="string" indexed="true" stored="true"/>
<field name="EntryType" type="string" indexed="false" stored="true"/>
<field name="_text_" type="text_general" indexed="true" stored="true" multiValued="true"/>
<field name="spell" type="textSpell" indexed="true" stored="true" multiValued="true" />
<!--<field name="content" type="text_general" indexed="true" stored="true" required="true" />-->
<copyField source="*" dest="_text_"/>
<copyField source="EntryEnName" dest="spell" />
<fieldType name="textSpell" class="solr.TextField" positionIncrementGap="100" omitNorms="true">
<analyzer type="index">
<tokenizer class="solr.StandardTokenizerFactory" />
<filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" />
<filter class="solr.LowerCaseFilterFactory" />
<filter class="solr.StandardFilterFactory" />
</analyzer>
<analyzer type="query">
<tokenizer class="solr.StandardTokenizerFactory" />
<filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true" />
<filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" />
<filter class="solr.LowerCaseFilterFactory" />
<filter class="solr.StandardFilterFactory" />
</analyzer>
</fieldType>
SolrConfig.xml
<lst name="spellchecker">
<str name="name">default</str>
<str name="classname">solr.IndexBasedSpellChecker</str>
<str name="field">spell</str>
<str name="spellcheckIndexDir">/path/to/my/spell/index</str>
<str name="accuracy">0.7</str>
<float name="thresholdTokenFrequency">.0001</float>
</lst>
<lst name="spellchecker">
<str name="name">wordbreak</str>
<str name="classname">solr.WordBreakSolrSpellChecker</str>
<str name="field">spell</str>
<str name="spellcheckIndexDir">/path/to/my/spell/index</str>
<str name="combineWords">true</str>
<str name="breakWords">true</str>
<int name="maxChanges">10</int>
</lst>
<requestHandler name="/spell" class="solr.SearchHandler" startup="lazy">
<lst name="defaults">
<str name="spellcheck.dictionary">default</str>
<!--<str name="spellcheck.dictionary">wordbreak</str>-->
<str name="spellcheck">on</str>
<str name="spellcheck.extendedResults">true</str>
<str name="spellcheck.count">10</str>
<str name="spellcheck.alternativeTermCount">5</str>
<str name="spellcheck.maxResultsForSuggest">5</str>
<str name="spellcheck.collate">true</str>
<str name="spellcheck.collateExtendedResults">true</str>
<str name="spellcheck.maxCollationTries">10</str>
<str name="spellcheck.maxCollations">5</str>
</lst>
<arr name="last-components">
<str>spellcheck</str>
</arr>
</requestHandler>
Now the error is gone . But when I call the url like
I got empty suggestions.
<lst name="spellcheck">
<lst name="suggestions"/>
<bool name="correctlySpelled">false</bool>
<lst name="collations"/>
</lst>
And Actually . I can search many results with the keywords lung. why solr doesn't suggest the Lung when I tried the lu? Anything I missed .Thanks.
