I have the following field type set up in my schema. The idea is to fire
phrases of text such as 'fund manager summary' (without the quotes) at it, and
for the synonym processing to recognise this, and add the rest of the synonyms
(index-time synonym processing with expansion) to the index from my synonym
file (example below)
<fieldType name="synonymstring" class="solr.TextField"
positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="solr.KeywordTokenizerFactory"/>
<filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt"
ignoreCase="true" expand="true"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.KeywordTokenizerFactory"/>
</analyzer>
</fieldType>
in synonyms.txt.....
fund manager summary, fund manager report
guide, product guide
I run into 2 issues...
(1) After analysis of the field in SOLR, I find that both
fund manager summay
fund manage report
are NOT getting picked up by the synonym factory (after processing I just get
the source term outputted from the synonym filter)
(2) If I analyse guide, I do get product and guide (*2) outputted from the
synonym filter factory - but as seperate terms (3 terms in total), I expected
it to generate just 1 additional term - i.e. product guide
It seems that it is able to pick up a single word and output two (as seperate
terms), but it fails to pick up multiple words.
Can anyone help? (incidentally when I use this approach on a SOLR text field
type it all works fine, but I cant use a SOLR text field type for this as I use
this field for facetting.
