Portable File Indexer (Windows)

[sjau]

Hi there

There are quite a few good file indexer around: strigi on kde, tracker on gnome (each can be used on the other), Google Desktop on multiplatforms, Windows Search....

However I'm currently looking for a portable file index that runs on widnows. Basically I have stored quite a few docs on my usb stick (encrypted of course) and I'd like to full-index them and have the db also on the stick and the indexing tool should be standalone.

Anyone has a suggestion here?
