Hi Z,
I wouldn't consider myself an expert, but I have a few comments regarding
verity. This feature is in my opinion extremely powerful and underutilized.
Having said that, it could definitely use some improvement. To be specific:
1) The verity search engine built into CF is somewhat stripped down from
the full version. Although, as I have learned from posts on this forum, the
version that comes with Cold Fusion is full of "undocumented features" that
coincidently turn out to be features in the full version :-O
2) To say the least, Verity can be weird.
I've definitely had my share of problems with Verity. Probably the worst
one of all is that it doesn't tell you when there's an error...it just
doesn't work. Here are a couple of other points from my presentation that
may help (If you do go looking for the entire presentation, its under PAST
MEETINGS > February > Eron Cohen):
--Verity searches can be CaSe sensitive. I typically force keyword searches
into lower case.
--When using CFINDEX you must be sure that all the fields you include in the
BODY= parameters are valid fields from your query. Often you won�t get an
error message and your index won�t work!
--There IS a limit to the size of your collections! This is documented in
Allaire�s KB (article #11934)
And possibly the biggest GOTCHA:
--**********ALWAYS make sure your KEY= field is unique for EVERY record. If
you don�t do this, as soon as verity encounters a duplicate key it will stop
indexing there (and it won�t give you any error messages!)***************
3) I have done quite a bit of indexing of large amounts of data. I am not
exactly sure what the limit is, but in fact, there IS a limit to the size of
your collections! This is documented in Allaire�s KB (article #11934).
This is something you can get around because in CFSEARCH you can name more
than 1 collection to search at the same time, so you can always break down
what you want to search into separate collections.
I recently gave a presentation about Verity searches at the Maryland Cold
Fusion user's group. You can download my PowerPoint slides there:

Subject: concerned about verity
I have heard from someone recently that the version of verity that
coldfusion bundled with its software is a very stripped down bare-bones
lite version, so much so that it will time out and crash if it has over
3,000 documents to search. This concerns me greatly because A) allaire
provides no documentation concerning the limits of the verity search
engine they bundled and I am using it in a few content heavy sites as
the basis of a search engine and theses sites can grow to over 3,000
documents easily. Any comments from experts on this?
