Blargy,
I've been experimenting with this myself for a work project. What I
did was use a combination of the two running the indexed terms through
the Shingle factory and then through the edge n-gram filter. I did
this in order to be able to match terms like :
.net asp c#
asp .net c#
c# asp .net
c# asp.net
for a word query like
asp c# .net
The edge ngrams are good, but they can also fail to match on queries
when the words in the index are in a different order than those in the
query.
My setup in schema.xml looks like this :
<fieldType name="edgytext" class="solr.TextField"
positionIncrementGap="100">
<analyzer>
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.ShingleFilterFactory" maxShingleSize="2"
outputUnigrams="true"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.EdgeNGramFilterFactory" minGramSize="1"
maxGramSize="25" />
</analyzer>
</fieldType>
Let me know how this works for you.
