Having thought about this problem domain too (see my old work on ZOQLMethod), 
there is a big difference between relational- and tree-based querying. I 
wonder whether you can get both covered -- would be awesome though. :-)

I would definitely be interested in seeing public discussion about the 
approach here. Some random thoughts that you probably know already:

* The storage of indices should be pluggable like the ZODB. This would allow 
backends like pyLucene, BTree-based ones or even relational databases.

* One of the big problems right now is that there is no efficient way to do 
inverses of searches. I think some time should be spent doing this.

* I really like the API of hurry.query. I would love to see something like it 
as the backend for querying languages.

I am really looking forward to what you will come up with!

Regards,
Stephan
