Searching for symbols with tsearch

Hi Guys,

I'm working with tsearch, but there's a problem with words with trailing TM
symbol or (C) symbol.  Tsearch will not stem these words, hence they are
unsearchable.

Eg:

6 Under 6 Salads (no dressing): Veggie DeliteT

Is indexed as:

'6' 'dress' 'salad' 'veggi' 'deliteT'

Where it really should be indexed as:

'6' 'dress' 'salad' 'veggi' 'delit'

Anything I can do about this?

Chris
