Ankur commented on PIG-732:
---------------------------

Not sure why the core tests fail. The automated test output don't seem to 
suggest anything patch specific or may be I am unable to spot in the console 
output.

> Two utility UDFs and their respective test cases.
> 1. TopN - Accepts number of tuples (N) to retain in output, field number 
> (type long) to use for comparison, and an sorted/unsorted bag of tuples. It 
> outputs a bag containing top N tuples.
> 2. SearchQuery - Accepts an encoded URL from any of the 4 search engines 
> (Yahoo, Google, AOL, Live) and extracts and normalizes the search query 
> present in it.
