Kennt jemand ein advanced search plugin das mit Thesis Theme läuft ?

Hallo und Guten Morgen
Bis 4 Uhr in der Früh habe ich an Search Plugins rumgebastelt. Nix geht.
I tried out the following plugins without success.

1.advanced search (dont work)
2.super search (works with some problems)
3.unleashed search (dont work)
4.search everthing (dont work)
5.Search API (dont work)
6.MySQL Search (dont work)
7.Highlight Search terms (dont work)
8.Relevansii (dont work)
9.WP search custom fields (dont work)
10.Search by category (works with some problems)
11.Enhanced Search Form (dont work)

and some more...
I am using WP 3.0.1 and the new Thesis (not the new beta)
I think thats not easy. No one works. Only 2 with problems and errors.

Vielen Dank
Roland
