FilterMatcher.match currently compiles a new Pattern instance every time a string is tested. This is inefficient when for example all cells in a table will be tested against the same pattern. Instead a single Pattern instance should be returned and be used by the caller for testing all relevant strings.

Change FilterMatcher.match so that instead of returning whether a string matches a pattern, it returns the compiled Pattern instance and lets all callers run the pattern.matcher(stringToFilter).matches() statement.
