Hi, I have misunderstanding about usage of SynonymGraphFilterFactory and
WordDelimiterGraphFilterFactory. Can they be used together?
I have solr type configured in next way
<fieldtype name="fulltext_en" class="solr.TextField"
autoGeneratePhraseQueries="true">
<analyzer type="index">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.WordDelimiterGraphFilterFactory"
generateWordParts="1" generateNumberParts="1"
splitOnNumerics="1"
catenateWords="1" catenateNumbers="1" catenateAll="0"
preserveOriginal="1" protected="protwords_en.txt"/>
<filter class="solr.FlattenGraphFilterFactory"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.WordDelimiterGraphFilterFactory"
generateWordParts="1" generateNumberParts="1"
splitOnNumerics="1"
catenateWords="0" catenateNumbers="0" catenateAll="0"
preserveOriginal="1" protected="protwords_en.txt"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.SynonymGraphFilterFactory"
synonyms="synonyms_en.txt" ignoreCase="true" expand="true"/>
</analyzer>
</fieldtype>
So on query time it uses SynonymGraphFilterFactory after
WordDelimiterGraphFilterFactory.
Synonyms are configured in next way:
b=>b,boron
2=>ii,2
Query in solr analysis tool looks so. It is shown that terms after SGF have
positions 3 and 4. Is it correct? I thought that they should had 1 and 2
positions.
Now when a perform such query "my_field:b2" then parsedQuery looks so
"my_field:b2 Synonym(my_field:2 my_field:ii)"
But for such query "my_field:2b" parsedQuery will be such "my_field:2b
Synonym(my_field:b my_field:boron)"
Synonym works only with last part of my query.
Am I doing something wrong? Or maybe this filters are incompatible?
