As you do not have an unnamed spellchecker, there is no spellchecker defined with the name 'default'. Hence its erroring out when its trying to get config for the non-existent 'default' spellchecker. I think it should work if you remove "<str name="spellcheck.dictionary">default</str>" from your '/spell' requestHandler? Hope that helps, Areek On Fri, Dec 6, 2013 at 11:33 PM, sweety <sweetyshind...@yahoo.com> wrote: > Im trying to use spell check component. > My *schema* is:(i have included only fields necessary for spell check not > the entire schema) > <fields> > > <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. > Thanks in advance. > > > > -- > View this message in context: > http://lucene.472066.n3.nabble.com/Null-pointer-exception-in-spell-checker-at-addchecker-method-tp4105489.html > Sent from the Solr - User mailing list archive at Nabble.com. >
