The entire fts subproject was only begun about a year ago, meaning
that fts2 has existed for much longer than fts1 had when it was
released - fts2 has certainly had more thorough testing at this point.
I can't think of any good reason to use fts1 at this point.

Admittedly, I haven't updated the wiki with this info.  I'll put that
on my list to get done.

realizing FTS2.

[sqlite] FTS-2

We have developed some user functions to generate key strings and these 
might be of interest to other users.  Basically they concanentate the 
columns of interest into a meta tag string then strip out noise words 
such as prepositions and punctuation, upshift the words and then update 
a column used for the FTS2 index.  A complementary function similarly 
processes a string to provide a compatible MATCH string.  Soundex 
versions of the words can be added.
