Hi, thanks for the response.
Label field:
<field name="label" type="text" indexed="true" stored="true"
termVectors="true" omitNorms="true"/>
<fieldType name="text" class="solr.TextField" positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="txt/stopwords.txt" />
<filter class="solr.WordDelimiterFilterFactory"
generateWordParts="1" generateNumberParts="1" catenateWords="1"
catenateNumbers="1" catenateAll="0" splitOnCaseChange="0"
preserveOriginal="1"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
<filter class="solr.NGramFilterFactory" minGramSize="3"
maxGramSize="25"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.SynonymFilterFactory"
synonyms="txt/synonyms.txt" ignoreCase="true" expand="true"/>
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="txt/stopwords.txt" />
<filter class="solr.WordDelimiterFilterFactory"
generateWordParts="1" generateNumberParts="1" catenateWords="1"
catenateNumbers="1" catenateAll="0" splitOnCaseChange="0"
preserveOriginal="1"/>
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
</fieldType>
I can surely optimize the above config a bit, maybe only use one
<analyzer> for both query and index. But for now, this is what it
does.
Just as a side-question: is dismax *supposed* to match fields exactly
with the search query? Or is my expectation correct, meaning it should
"tokenize" the field, just as with regular searches? It just doesn't
seem intuitive to me.
Thank you again for your help.
Kind regards,
Wouter Admiraal
