Could fts3 (the next fts) have the option to override the default
'match' function with one passed in (similar to the tokenizer)?
The reason I ask is then the fts table could be used as smart index
when the tokenizer is
something like bigram, trigram, etc. and the 'match' function computes
Besides the suggestions from Dennis below, please search the archives

It's all interesting, but categorization is hard. Not so hard to get
some results, sort of hard to get quality results. Might work as a
nice adjunct to fts, so that you can throw the search terms into the

What folder are you in at the command prompt when you type "SQLite3
mydatabase.db3"?
Does it actually contain SQLite3.exe? If not, you need to specify the full
path, or navigate to the folder first.

hoping that someone may have some tricks/hints on how to implement fast
