Sorry Chris, I only write this followup to the sword-devel thread.

Sorry for all the typos last night. Was running on coffee.

So, I spent a little time this afternoon adding in the index field
discussed in this message.  It's committed in SVN.  You'll need to
rebuild your indexes on a module to take advantage of it.  Nothing
should be disturbed if you don't, but you won't have the new field
available.

The field is called 'morph'.  You can see it in action on swordweb:

http://crosswire.org/study/parallelstudy.jsp

At the top, under 'Presets' click 'NT Scholar'

Click on any word in KJV, TR, or Tregelles.

You'll notice a few new options now.  You can search for the lemma with
any morphology-- how things have worked for a long time.
Or you can now search for the lemma with the same morphology as the word
you clicked-- this uses the new morph index field.

Once you've done a search, you can see the search string that was built
and can play around with ? and * on the morph, or any of the other
lucene functions you find here:

http://lucene.apache.org/core/3_6_0/queryparsersyntax.html

One caveat: '-' is common in Robinson's morph codes and needs to be
escaped; it means 'without' in lucene search syntax.  bummer.

Have fun, let me know what you think.
