Roy,

<< However, I see "Text search on non-indexed columns" isn't available in

I hope that the alternative isn't using lots of LIKE's >>

It's the same thing, essentially, except that LIKE is faster.  IOW, there is
no benefit to the full-text indexing without the "indexing" part. Smiley

I'm accessing it with FF 2.0.0.1 and it looks just fine.  I'll try it with
2.0.0.2, but I doubt if I'll see any difference.

But its a lot easier to generate a TEXTSEARCH for a wadge of words rather than to 1) determine wether or not this column has a text index and if not generate a load of LIKES.

Just being lazy again

Actually, it's very simple.  Try using CONTAINS or DOES NOT CONTAIN on a
non-text-indexed column.  You'll get an error. Smiley

To be honest, this all goes back to the fact that the full-text searching in
EDB is more closely-tied to the parameters used to build the text index.  I
believe this was a step forward, even though the brute-force text searching
was lost in the process.  It's more flexible than the old text indexing in
DBISAM that was tied to the table instead of the index/column.

Well, you shouldn't be allowing them to perform full-text searches on
columns that aren't indexed. Wink

Whoops, I just looked again and I forgot to put in the actual error when an
index doesn't exist.  Right now it simply returns all rows.
