Subject Re: weird problem with letters S and T
Date Wed, 28 Oct 2009 22:42:51 GMT
I think that is not a problem, because your are only storing one
character per field. There are other text field types that do not have
the stop word filter, so give your first letter field that field type.
In this way stopword filter analyser is only disabled for searches on
the first letter field.

Cheers,

Martijn
