Hello!
I am very glad to hear that you like tiedot.
Did you mean using regular expression to filter certain attribute in query result? For example, matching /(good)|(average)/
in document's "grade".
from tiedot.
Yes, or more complex: /[AF]/ in document's "grade". The high and low performers. Or again, to do wildcard searching,such as
- all names ending in the letter "n": /n$/
- all codes beginning with a letter and ending in a digit: /^[0-9].*[A-Z]$/
Since Go has a regexp package (http://golang.org/pkg/regexp/), I thought it would be pretty easy and would be nice addition the current eq, range, and set operations. In SQL I use wildcards a lot and noticed the absence in tiedot right away.

Oh! I see.
In that case, I am afraid that index scan cannot help much at this stage, regex filter can be applied in collection scan (which is still quite fast).
from tiedot.
So would it look something like this?
q='{"re": "Go|Clojure", "in": ["Title"]}'
to find every title with either "Go" or "Clojure" in the title.
Thanks for considering,
Cecil
