Search API Not Working

Search API Not Working

I was trying to search job openings based on conditions but i was not able to get any results for any kind of expression but when i use the same auth token to get the list of Job Openings it works fine.
 
Job Listing request URL:
https://recruit.zoho.com/recruit/private/json/JobOpenings/getRecords?authtoken=auth_token&scope=recruitapi&version=2&newFormat=1
 
Search request URL:
https://recruit.zoho.com/recruit/private/json/JobOpenings/getSearchRecords?authtoken=auth_token&scope=recruitapi&selectColumns=All&searchCondition=(PostingTitle|contains|*vel*)
 
Please let me know how to search with associated tags on the Job Openings because this field is not listed in the API documentation.
