I thought we agreed that situations where the cardinality was different
(eg A,B search against A,B,C fields) wouldn't work? And this is only true
if the node does the matching, which it might not have to do, if all the
matching terms are returned and the client filters them.

We can write a Freenet for Dummies, that includes the URLs of the JRE
packages (which are self-installing executables):
Windows:
http://java.sun.com/j2se/1.3/jre/download-windows.html
Linux:
http://java.sun.com/products/jdk/1.2/jre/download-linux.html
Solaris:

Macintosh:
http://asu.info.apple.com/swupdates.nsf/artnum/n11572
OS/2:
http://www.ibm.com/java/jdk/JREsite.html
That should cover the bases.

If the metadata keywords would be one way hashed, each separately, this
would ofcourse not provide full fuzzy logic, but would still be better than
nothing, and would hide the information from the node containing the
meta-data. Another one is to do a weak enough hash that partial match can be
detected, I'm not sure if this is possible but I can imagine it being
possible.
Other options are to random xor the meta data and give the result to one
party, and the random key to another, when one of the parties gets a meta
data query he xors it with his own key, and sends the xored value to someone
who has the other part of the key, and he performs comparison on the keys.
Ofcourse this would require a bit more trafic but the meta data would be 99%
hidden, and full fuzzy logic could be exploited in the meta data search.

It wouldn't be hidden at all. If the server knows how to find the other
half of the key, then this system is useless, because the node operator
knows (or can find) the other half as well. This provides no additional
security.
Likewise, any weak hash that can allow the server to perform fuzzy
matching isn't strong enough to warrant its use, since its not going to
provide any measure of deniability.

We hash things normally so as to make sure that the routing of
information does not reflect the content of the
(descriptive) keys. However, with searching this is the point, so
hashing makes little or no sense.

I don't think we agreed on anything.. we should try out all possibilities
in a simulator first. I originally thought that AB against ABC would be fine for
returning results, but not for routing, but my latest idea (not written up yet)
uses slightly different routing anyway.
