I have a database now with 1.77 million entries using Tsearch. The entries are book titles. It runs
very well. There are some tricks to it though. For example what we had to was have a single
table that has nothing but a product_id, title, title_vectors.

Then on a search, we return the product_ids and grab the titles from the detail table via the product_ids
that were pulled from the search.

Mnogosearch was scrapped due to it's speed (or lack thereof), and iirc,
tsearch2 closely resembles the same type of mechanism for full text
searches. Just something to think about.

Btw, With regards to the forums, I imagine they'll come back over the
weekend...

What are the thoughts on this?

Sincerely,

Joshua D. Drake
