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.
