<field name="doc_id" type="uuid" indexed="true" stored="true" default="NEW" multiValued="false"/> <field name="id" type="string" indexed="true" stored="true" required="true" multiValued="false"/> <field name="contents" type="text" indexed="true" stored="true" multiValued="false"/> <field name="author" type="string" indexed="true" stored="true" multiValued="true"/> <field name="title" type="text" indexed="true" stored="true"/> <field name="_version_" type="long" indexed="true" stored="true" multiValued="false"/> <copyfield source="id" dest="text" /> <dynamicField name="ignored_*" type="text" indexed="false" stored="false" multiValued="true"/> <field name="spelltext" type="spell" indexed="true" stored="false" multiValued="true" /> <copyField source="contents" dest="spelltext" /> </fields> <types> <fieldType name="spell" class="solr.TextField" > <analyzer type="index"> <tokenizer class="solr.WhitespaceTokenizerFactory"/> <filter class="solr.LowerCaseFilterFactory" /> <filter class="solr.EnglishMinimalStemFilterFactory" /> <filter class="solr.SnowballPorterFilterFactory" /> <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" splitOnCaseChange="1"/> </analyzer> <analyzer type="query"> <tokenizer class="solr.WhitespaceTokenizerFactory"/> <filter class="solr.EnglishMinimalStemFilterFactory" /> <filter class="solr.SnowballPorterFilterFactory" /> </analyzer> </fieldType> </types> My *solrconfig* is: <searchComponent name="spellcheck" class="solr.SpellCheckComponent"> <str name="queryAnalyzerFieldType">text</str> <lst name="spellchecker"> <str name="name">direct</str> <str name="field">contents</str> <str name="classname">solr.DirectSolrSpellChecker</str> <str name="distanceMeasure">internal</str> <float name="accuracy">0.8</float> <int name="maxEdits">1</int> <int name="minPrefix">1</int> <int name="maxInspections">5</int> <int name="minQueryLength">3</int> <float name="maxQueryFrequency">0.01</float> </lst> </searchComponent> <searchComponent name="spellcheck" class="solr.SpellCheckComponent"> <lst name="spellchecker"> <str name="name">wordbreak</str> <str name="classname">solr.WordBreakSolrSpellChecker</str> <str name="field">contents</str> <str name="combineWords">true</str> <str name="breakWords">true</str> <int name="maxChanges">10</int> </lst> </searchComponent> <requestHandler name="/spell" class="solr.SearchHandler" startup="lazy"> <lst name="defaults"> <str name="spellcheck">true</str> <str name="spellcheck.dictionary">direct</str> <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">5</str> <str name="spellcheck.collate">true</str> <str name="spellcheck.collateExtendedResults">true</str> </lst> <arr name="last-components"> <str>spellcheck</str> </arr> </requestHandler> I get this *error*: java.lang.NullPointerException at org.apache.solr.spelling.*ConjunctionSolrSpellChecker.addChecker*(ConjunctionSolrSpellChecker.java:58) at org.apache.solr.handler.component.SpellCheckComponent.getSpellChecker(SpellCheckComponent.java:475) at org.apache.solr.handler.component.SpellCheckComponent.prepare(SpellCheckComponent.java:106) at org.apache.solr.handler.component.SearchHandler.handleRequestBody(SearchHandler.java:187) at org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandlerBase.java:135) at org.apache.solr.core.RequestHandlers$LazyRequestHandlerWrapper.handleRequest(RequestHandlers.java:242) at org.apache.solr.core.SolrCore.execute(SolrCore.java:1797) at org.apache.solr.servlet.SolrDispatchFilter.execute(SolrDispatchFilter.java:637) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:343) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:141) at I know that the error might be in addchecker method,i read this method but the coding of this method is such that, for all the null values, default values are added. (eg: if (queryAnalyzer == null) queryAnalyzer = checker.getQueryAnalyzer(); ) Now so i feel that the Null checker value is sent when /checkers.add(checker);/ is executed. If i am right tell me how to resolve this,else what has gone wrong.
