This problem is like this:Solr wildcard query with whitespace I have a wildcard query that looks something like:
q=location:los a*
I'd like it to match "los angeles" and "los altos". A query like:
q=location:los\ a*
Works fine, but if I have a synonym logic:(synonym.txt)
los,las
And use "los l*" to match "las lu".Seems not work.How can I do this?
The fileType and 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">
