I have some tweets and I need to know if any of these tweets contains any phrase (or part of phrase) from the Quran.
A friend told me this is a full text search job and he advised me to use elasticsearch for that.
I have installed elasticsearch and indexed all the Quran phrases. I think to achieve what I want, I need to get the intersection between the tweet body and the phrases.
Is this the correct approach?
If yes, how can I do that?
If no, what other approaches can I look for ?
