Additional information & file uploads

Search delay has been set to 7500 ms and I wasn't rate limited.
I used the pattern field to use regex matching to delete particular messages. The expression was in this format: (word1|word2|word3)

Additional Info: I tried this script thrice and it fails to delete messages after 10000 messages. Hence I have arrived at the conclusion that it fails after the 9999 limit
