Ruby Forum Ferret > Ferret index internal strutures documentation

Hi List,

I'm new to Ferret, so appologize if the question was already asked
before.

I'd like to know if there's a good technical documentation about
Ferret's index internal structures (inverted index in disk, skip list
...).

I know that the index is created in C, and I'm interested on that.

Thanks in advance

Regards

Y.
