It would please me! -the majority of the queries that I want to make are 
of this form, and it would save having to create adql for the purpose....

I also think that Yuji Shirasaki's idea of having a search that returns 
a list of identifiers for a query is a potentially good one, and 
possibly even a function that returns the number of matches for a query. 
- This could of course be done with a single query interface function 
but with a slightly extended RQL
