Hi everyone!
I'm having a problem and I have searched and Haven't found a solution yet
and am rather confused at the moment.
I have an application that stores human readable texts in my Solr index.
It finds the most relevant terms in that human readable text, I think using
termvectors and facets, and it stores the facets terms.
All works fine but now I need that the most relevant terms can also be terms
of at least two words, like "European Union", which is quite a frequent term
in my system...Still the system is getting into the facets "European"
"Union" as two separate terms.
So, questions are:
- Is it possible to have facets of two or more words?
- Can I tokenize a phrase into words, but when it comes accross "European
Union", it generates one token for "European Union" and not two tokens
"European Union"?
- Can termvectors be used to find relevancy of multi-word terms like
"European Union" ?
- Can I use SynonymFilterFactory that would transform: "EU, UE, European
Union, Union Europeene" into "European Union" ?
At the moment of indexation I have the following analyzer for english
language:
<fieldType name="text_en" class="solr.TextField" positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.StopFilterFactory" words="blacklist.txt"
ignoreCase="true"/>
<filter class="solr.LowerCaseFilterFactory" />
<filter class="solr.SynonymFilterFactory"
synonyms="synonyms.txt"
ignoreCase="true" expand="false"/>
<filter class="solr.StopFilterFactory" words="en"
ignoreCase="true"/>
<filter class="solr.HunspellStemFilterFactory"
dictionary="en_GB.dic" affix="en_GB.aff" ignoreCase="true" />
</analyzer>
</fieldType>
Thank you for the help!
