search bug? [message #168185] Thu, 21 February 2013 18:18 Go to next message

I just installed about a month ago and starting posting some test messages. When I do a search sometimes I get correct results but mostly I just get nothing depending on the word searched. Its almost as if some words are in the search index and some are not. I am searching normal words like "child", "health", "survey", etc... some work, but most do not.

I did a rebuild search index from admin but that did not help. I also tried changing the search cache to smaller or larger values. That did not help either.

Any suggestions? Thanks.

Bob

Update:

We have nearly 100 messages in the system but there are only 70 words in the search table. Many many words are missing. Rebuilding the search index seems to have no effect. Still 70 records after each rebuild.

Any ideas what might be going on here?

Thanks.
Bob

I think I may have this partially figured out. There is a unique contraint on the "search" table. This causes a db error when inserting duplicate words and stops the rebuild process. I dont know why the system is attempting to insert dupes but apparently it is. I turned the unique contraint off and rebuilt the search index and then all the words were inserted "correctly"... with dupes of course, but at least all the words are in there now and the forum search now seems to work.

I think this function is not working correctly: $w2 = array_unique($w2); (in isearch.inc)

Is there a better workaround than what I have done or is there a fix for this?

Thanks.

It appears that the $w2 array is multi-dimensional and array_unique is not intended for multi-dimensional arrays. So I dont really know how to deal with dupes in the word list. It seems to work fine with the dupes there but just needed to make sure the search table in the database allows for duplicate entries in the word column. The standard FUDforum install for MS SQL Server puts a unique restriction on that column.
