> A new Pig UDF *STRING_SEARCH_ALL* that Implementing regex for searching
> keyword(substring) in a line of string, and all matched substrings will be
> stored as individual tuples in a bag, i.e.{code} output: ({(a),(b),(c)}){code}
> Help us to find all regex matches, for example, we may use
> *FLATTEN(STRING_SEARCH_ALL(string, regex))* to list all matches for an easier
> view of output.
