Thanks - that was very helpful.

Yes, that would be reasonable.  I've just done a quick investigation of 
what happens, and found the problem; we don't currently cope with mixed 
stemming settings correctly.

If you try setting all the field actions to use the same language, or 
all of them to use no language (so no stemming), it works as expected. 
However, when any of the fields have a stemmer, the query parser fails 
to build the search terms for those fields correctly.

I can see a "quick hack" solution, but I'm not certain it won't degrade 
performance elsewhere, so I'll do a few tests to check on that.  I'm 
hoping to have time in the near future to do a clean-up of the way in 
which the field settings are set, which will make this kind of conflict 
impossible to happen, so I'm not going to spend too much effort on a 
short-term solution, though.

For now, I suggest you use the same stemming strategy for all free text
