Hi,
I'm trying to see if an array of strings contains any elements that match a regex using the Criteria object.
Criteria.regex(String) works fine for single-valued string fields, and Criteria.in(Object) works fine for string array fields, but how do I combine in() with regex()? If I pass a string containing a regex, I get no matches. Here's a snippet of the mongo log, showing that the regex is not slashy (look for $in operators below):
The java source for the above query uses Criteria created like this (where regex is a string containing the regular expression):
This appears to be supported by Mongo since version 1.3.4: https://jira.mongodb.org/browse/SERVER-322
Should there be a Criteria.inRegex(String... regexes) method?
Thanks,
Matthew

where("user.person.surnames").in(regex)Should there be a Criteria.inRegex(String... regexes) method?
