I found better solution - simple and amazing plugin - https://marketplace.atlassian.com/plugins/eu.kprod.jira.stattable-searchers- adds additional searchers, including exact searchers - for custom fields.
It also makes it possible to use these fields as dimensions in 1- and 2-dimensional statistics gadgets on the dashboards.
You'll need to write a new searcher to do this. It should be a moderately simple plugin to write (not that I'm sure it's particularly useful).
Stuff on writing searchers is entwined with custom fields (As that's what they search) - see https://developer.atlassian.com/display/JIRADEV/Custom+Field+Plugin+Module
