Fulltext Search for .doc & .pdf on Asus Transformer

[warry]

Hi!
I'm searching for some apps for my Asus Transformer TF101 (Android 3.2.1, not rooted) to make studying easier.
Most important to me would be a fulltext search app, to search the content of my local documents and pdf-files.
I've already tried Document Search (didn't find any file, creating an index seems to fail), Fast Search (no fulltext), InFileSearch (no dependable results, Design doesn't fit) and some file manager (no fulltext).
Unfortunately Power Search isn't compatible with my Transformer.

So, do you have any idea how to search the whole content of my local files?


One more thing: Is there any high quality pdf converter which doesn't send my files to a server and which doesn't cost nearly 10$ like the App from Adobe?

No one got an idea? It would be really important to me!
I just can't imagine that there isn't a fulltext search app anywhere in the net...
