Test indexers...how do they work?

[Raja Raman Sundararajan]

Hello guys,
    I was investigating how one can use the "text indexers" in python
and I stumbled across several ones. eg., pylucene

I wanted to know how the algorithm of indexers look like. I have heard
people talking about B-Trees. But this info. is simply know enough. I
would like to know exactly each part of the indexing flow and the
algorightm behind it work.

Can someone here point me to the right material?

Thanks!
