Find occurrences of huge list of phrases in text

Question

I\'m building a backend and trying to crunch the following problem.

• The clients submit text to the backend (around 2000 characters on average)

Answer 1

Maybe you should try flashtext.
According to the author, it is much more faster than Regex.

The author even published a paper for this library.

I've personally tried this library for one of my project, in my opinion its API is quite friendly and usable.

Hope it helps.
