Mobile phone (iPhone, Windows CE, Symbian, Android) search engines (text indexers)?

Question

I'm looking for search engines that will run on one or more of the mobile platforms listed in the title.

Something like Lucene (which 'should' run on Android) or minion.

What are my alternatives on each platform? Have you made them run? What are the limitations you stumbled upon (cannot index more than 20 megs, for example)?

Answer 1

There are some smaller and lighter Java search engines, that might be the way to go.

And now I'm fascinated: if you could, please tell me more about what you want to index and search on a mobile phone. Personal data? Cached html pages? Recipes?
