Word de-compounding using the terms in the index?

[mtraynham <mt...@digitalsmiths.com>]

Say for instance at query time, I would like to use the terms within my index
to de-compound query Terms.  The current solution I'm aiming for is to build
a "suggester" like component into the query pipeline using TSTLookups. 
Since all Lookups require to be SolrCoreAware, that is; rebuilt when commits
happen, is it feasible to keep a Lookup hash for certain fields stored in an
Query Parser Attribute and pass that down to a certain piece in the
pipeline?  Then it would decomp the terms as needed...

Is this feasible, or will I see my hash blow my memory out of the water?  If
I could achieve the same result using a Field filter factory, I would, but
I'm not sure if they are allowed to be SolrCoreAware.
