Comment 4 for bug 580163

Is there some description of what bloom filter in ADC does? ADC specs says only how they transferred, but I'm curious in this exact case. Does it work in following way?

- client searches for TTH
- hubs has this TTH in blooms, so it doesn't have to redirect search request to users
- hubs sends response to the client

If it works in this way then partial sharing would require hub support, but it uses special RES format.
If it doesn't work in this way then I don't understand it at all. Also wikipedia says "False positives are possible, but false negatives are not.", so bloom filters can't return that file is not shared although it is.
