> 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.
