Search by Multiple Values w/ Contains
This snippet extends the “contains” operator to support comparisions where a multi-value field (like a Multi Select) is the needle. Typically, the “in” operator would be used for this; however, it has the limitation of only being able to match full values rather than checking if any of the needles are contained in the haystack.
