[storm] Building large queries with Storm ORM

[nhytro-python at web.de]

I have to code an extended search for a site, the search criteria can be built from large groups of values which are retrieved from checkboxes. I have 4 groups and each group has at least 10 checkboxes, each group result has to be joined with the next to acheive the final result.

My question is, how can I build such a query using the Storm ORM to search tables? Some of the values in the checkboxes would be "None" so I cant have a definite number of substitution Strings, and joong all of them afterwards makes my head spin.

Doe someone have a snippet for me on how I could acheive this?

Thanks
