Frank McQuillan commented on MADLIB-984:
----------------------------------------

I'd suggest we do this before any other Path phase 2 stories since it will simplify the code base and make it easier for developers to add subsequent features to path.

> The UDF to be implemented will obtain the matching indices in sym_str, which is in turn used to filter {match_to_row_id}  for matched rows. 
> This implementations pipeline operations directly in {matched_partitions}  and remove the need of creating and joining two extra tables/views {length_of_matches} and  {length_of_between_matches}.
> Boost.Regex can be helpful for implementing the proposed UDF:
