A while back I sent a note about strange search behavior in MediaWiki 1.3. Basically, when we search for some strings, we get back very limited partial search results. In the interim, we upgraded to MediaWiki 1.3.0beta6 and MySQL 4.0.18-standard, but are still having similar issues. Here is an example of the problem: When we search for the terms "pids", we get the following results: For query "pids" No page with this exact title exists, trying full text search. Fids 75% (****) MediaWiki (or MySQL) seems to give up on "pids" and go for a match on "Fids". If I do a search for "PIDS" (all caps), these are the results: No page with this exact title exists, trying full text search. Showing below 24 results starting with #1. Article title matches Music PIDs (888 bytes) Pids For Various Products (4662 bytes) ... Page text matches Sandbox (41 bytes) Reserved Pids (1089 bytes) ... So, there are a lot of pages that match "pids", but depending on how you enter the query you get very different results. Does anyone have an idea as to why this is happening? I can provide more strange search results if needed... -Matt
