Field filtering on range strings or on multiple values with the same value string
Description
It is possible to filter a field using the strings in its value string, which matches against the first entry with that string. (If there are multiple fields with the same abbreviation, I believe it picks the first value string.)
It would be nice to be able to filter on the strings in range strings, and on all values that have that string. It might be easiest to implement this just for the membership operator (in {...}), though also supporting equality, and supporting other comparisons via either "all" or "any" logic would be nice as well.
