Functionality for matching strings by portion of a string (db agnostic pattern matching mechanizm)?

[akrsmv]

I was thinking also for a pattern matching implementation in some of the new versions. I mean - would it be possible to extend the seneca-standard-query (or is it there already, and i missed it?) with a functionality like this:

entity.list$({stringProp:/some_portion_of_a_value/, ...}

I understand that implementing it with a regex would be very hard having in mind specific implementations of the db stores but, probably an implementation as simple as indexOf(pattern) > -1

It is a common functionality for all db stores.

I think that existing standard-query + count$ (feature request) + pattern marchers (this request) would already cover >90% of the web application needs
