Watch out for performance problems with Evo queries. The last version
I tested defaulted to sending massive 'OR' queries asking for
substring matches on about 50 (!) attributes. This completely defeats
any query optimisation you might try to do with indexes. On a
directory with any non-trivial amount of data, this will result in
heavy CPU load and probably memory thrashing as well.
