I would like to propose the addition of some reserved tags in SRW at the
level of <SRW:records> to allow for unsollicited response items like
fuzzy match terms and an index scan. The rational behind this is that
while CQL is quite complex to deal with in metasearches, it would be
convenient to have the possibility to have a broad query and let the
server decide the best response. An example will be search for any and
let the server return how many hits there are for each index.
This would need the "creativity flag" that was talked about before. How
servers will be creative should however be strictly specified.
PS I will be leaving in 5 minutes and won't be able to read my mail for
a three days.
