Solr wildcard query with whitespace and synonym -


this problem this:solr wildcard query whitespace have wildcard query looks like:

q=location:los a*

i'd match "los angeles" , "los altos". query like:

q=location:los\ a*

works fine, if have synonym logic:(synonym.txt)

los,las

and use "los l*" match "las lu".seems not work.how can this?

the filetype , file config:

<fieldtype name="ngram" class="solr.textfield" positionincrementgap="100"> <analyzer type="index"> <tokenizer class="solr.whitespacetokenizerfactory"/> <filter class="solr.worddelimiterfilterfactory" stemenglishpossessive="0" generatewordparts="0" generatenumberparts="0" catenatewords="1" catenatenumbers="0" catenateall="0" splitonnumerics="0" preserveoriginal="1"/> <filter class="solr.asciifoldingfilterfactory"/> <filter class="solr.synonymfilterfactory" synonyms="synonym.txt" ignorecase="true" expand="true"/> <filter class="solr.lowercasefilterfactory"/> <filter class="solr.edgengramfilterfactory" mingramsize="1" maxgramsize="25"/> </analyzer> <analyzer type="query"> <tokenizer class="solr.whitespacetokenizerfactory"/> <filter class="solr.worddelimiterfilterfactory" stemenglishpossessive="0" generatewordparts="0" generatenumberparts="0" catenatewords="0" catenatenumbers="0" catenateall="0" splitonnumerics="0" preserveoriginal="1"/> <filter class="solr.asciifoldingfilterfactory"/> <filter class="solr.lowercasefilterfactory"/> </analyzer> </fieldtype>

<field name="location" type="ngram" indexed="true" stored="false"/>

you used solr.synonymfilterfactory indexing not query analyzer so

when search "los l*" looks terms starting los not "las". use analyzer query

add line query analyzer

<filter class="solr.synonymfilterfactory" synonyms="synonyms.txt" ignorecase="true" expand="true"/>

hope works
