Undocumented regexp matching is confusing

Issue Description

"string contains string" actually uses Parse.Query's .matches(str,'i') specifier, which is not documented and can cause problems because various punctuation has special meaning in regexps. However, as regexps are also very useful, it would be best to keep this feature while renaming it "matches" or "matches regexp" or "matches pattern" or "regexp" or "pattern", while also have a separate choice called "contains" or "contains substring", which would match a regexp produced by :

function escapeRegex(s:string):string {
    return s.replace(/[-\\^$*+?.()|[\]{}]/g, '\\$&')
}

Steps to reproduce

Filter a string field with a "string contains string" clause (in any version of Dashboard in which it still works, e.g. 4.0.0) ; search using a . in place of any specific character, which will find your items anyway ; then try searching for ( in a string column that has that character : searching for \( finds those items even though no \ is in that column, and searching for literally ( finds 0 results.

Actual Outcome

"string contains string" searches for regexp.

Expected Outcome

"string contains string" would search for a substring, another option would search for provided regexp.

Good find, yes, a proper renaming makes sense here.
