Help with speeding up regex

[eversuhoshin]

Hello, I am reading in financial filings to see whether the information I need is in the financial filing. I used regex to get rid of those documents that I do not need to examine. My matching regex uses tons of "or" and counts up false positive words/ phrases. However, using lot of "or" slows perl down so much. I was wondering if there is a way to speed up the matching process. Thank you so much!

here is the code. I slurp the filing and then make into a one long line and then do the matching
