When we try to search 'hai!' word it gives this error 115 /webinator/newstest/newsSearchFeed:83: Query `hai!' would require post-processing: Term `hai!' only partially matches index expression(s)
You probably do not have the exclamation indexed. You can either index it, allow post-processing, or leave as is, in which case it will effectively search for "hai" in the index, and return those matches.
