Hi there,
I wanted to clarify if FTS could provide any optimization for substring matches
like '*ion*' or similar?
That is, does it only scan the token index for matching tokens to locate the
main table records that contain those tokens, or does it do a full table scan
of the main table?

No. I think it will actually search for tokens that start with the 4

I read that the right tokenizer may help. Are there any open source ones out
there?
Please try the latest code checkin (
http://www.sqlite.org/src/info/e569f18b98) and let me know if it works any
better for you.
Thanks. I've already adjusted the code to manually assign keys, but I'll try to
get back to checking it.

I gather sqlite3_last_insert_rowid doesn't play well with FTS? I don't see an
exception noted in the docs but neither are there non-manually managed examples.
I'd prefer not to manually mange them but ...

Hi,
FTS and sqlite3_last_insert_rowid do not work together. This is a known
shortcoming. Basically this also means that you can't use any triggers
involving FTS.

virtual table creation, the fts virtual table retains all the expired data.
In this case do you drop the fts table and recreate it, or try to delete
rows in the fts table?
I would gladly get all this info from docs and not bother you, but the docs
on sqlite fts don't have

Just delete the rows in the FTS table.

Drake,
if I do this, I get: SQL logic error or missing database.

Hi all,
I'm sure I'm doing something stupid here...
CREATE VIRTUAL TABLE example USING fts4(TOKEN, CONTEXT);
INSERT INTO example(TOKEN, CONTEXT) VALUES('one', 'This is just one
sentence.');
INSERT INTO example(TOKEN, CONTEXT) VALUES('two', 'This is just one
sentence. Sorry, it
Quoth Gert Van Assche ger...@gmail.com, on 2011-04-13 22:35:49 +0200:
SELECT snippet(example, '[', ']') FROM example WHERE CONTEXT MATCH
(SELECT TOKEN FROM example);
You're asking to match a single independently arbitrarily chosen token
from anywhere in the table (which is not even the
1 - 100 of 213 matches
