Substring function or updated regex function

I know there is regex for substring searches, but considering the amount of time it takes to process, I have a feeling it is not using the best algorithm for the job when all you want is to search for a substring.

I think there should likely be a dedicated substring function, or regex should have some method of identifying when a person only wants to find a substring match, so it can use a lighter weight formula in the background.

Hi @Andrew_Adkins ,
usually Regex is the quickest possible way to deal with strings search/manipulation.

I always tend to rely on Regex (not only in Coda) for the extreme flexibility and the performance.
Could you please tell what “processing time” you are experiencing?

How big is the source you are searching from?
Ideally, sharing your document (or a sample) would help.

Thank you!
