FOSS gamedev and creative worlds

Forum's advanced search can't find all requested topics.
Example, you try to find world potions in Topic titles in Mods section:
[url]http://forum.minetest.net/search.php?keywords=potions&terms=all&author=&fid[]=46&sc=1&sf=titleonly&sr=topics&sk=t&sd=d&st=0&ch=300&t=0&submit=Search[/url] you will get only 3 result: [Mod] Pep: Player Effects Potions [1.2.0] [pep], [Mod] Potions [heal_potions] and [Mod] Potions mod [0.1] [potions]. But google will show another results with "potions" in topic title http://www.google.com/#q=minetest+potions+site:forum.minetest.net. So forum advanced search not showed all topics. Is this bug?

It is terrible. I tend to use http://krock-works.16mb.com/MTstuff/modSearch.php or google

But forum search still need to be fixed. It must show all results. Or mod developers will create duplicates of the same mods at least.
