I hope this question is all right for here. I tried to search the sub, but I'm not really sure what to search for to begin with, so here it goes.

​

I'll have a database full of posts that have a description, tags, and the body text. I want to create a suggestion functionality where the user clicks a button, select their preferences and receives a number of suggestions based on what they chose or the other posts they liked, etc.

I don't know what can be used for that, what solutions etc, that's why I need your help!

I know elasticsearch have this kind of functionality, as I've seen it being used at my work, but it was for a gigantic pool of items, so maybe it's overkill? Or maybe there's a better solution focused only on suggestions?

​

Thanks a lot!
