Good idea. However, I don't think it solves the actual problem (yet). ItemSearchJob is still an Akonadi::Job, and those are sequentially scheduled by Akonadi::Session. So, you'd still "block" the session while waiting for the results. This probably can be solved by making the job scheduler in Session aware of jobs that don't communicate with the Akonadi server.

Regarding the query language support other than SPARQL, the possible use-case here would be searching on IMAP or LDAP servers via the search interface of resources.
