Thanks for the explanation. Is there any way (other than the stopwords) of compressing this table? Or is it always as efficient as it can be, and you can't make it smaller without losing information?

There is an entire series of posts all about the search function so there's plenty to digest. I'm using most if not all of these techniques on my largest board right now, and it has nearly 400,000 posts. I think we're in good shape all the way up to a million at this point. :) Hi, Mori, welcome to the phpBB Doctor blog.

I have been busy with other things for a bit. Fulltext is a MySQL feature. phpBB is not a MySQL only system, so they (from what I can tell) implemented this system to be portable. There have also been tests that suggest that for some cases this algorithm can be more efficient. There have been a number of posts in the 2.0 phpBB Discussion forum at phpbb.com that talk more about this. Hi, Stephen, and sorry for the delay in approving your comments.

You're accomplishing this on the application level, which seems the wrong level. And by that I mean database, table-level fulltext indexes.

This seems very inefficient. So…. why don’t you guys use fulltext indexes instead? This seems very inefficient.

The page 2 says ... oh god, it works now. Nice. Some time ago it was not working. I was going to complaint, but found that some search queries were limited intentionally.

Part II talks about the search "stopwords" file, how it can be used to trim down the amount of space taken, and a MOD that I plan that will make it more efficient. I will try to cover the search_id in a later post. I think I have plans for parts II, III, IV, and perhaps V. There is a lot to talk about with searching. :-) As far as phpbb.com only allowing one page of results, that's probably not intentional. :-) I made a comment regarding the MOD Search utility some time back doing that, and it got fixed. I have not tried to use more than one page of search results using the regular search. Welcome, olpa, and thanks for your comment.
