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

Assuming that the list of phrases changes over time and gets bigger, I'd recommend using a software, that already does, what you need. E.g. elasticsearch, it's open source and has a Python client. If running a service like that in the background, this solves all you want and probably more than you ever can imagine. Also it's really not that hard to implement.
