My experience has been that if search isn't critical to the core of your business, you should use Algolia. What I mean is that good search is hard and expensive to build, and if your product will not suffer from good enough search then it will be an order of magnitude cheaper. I use it to search over a list of 25k ish items that can be ordered broken into 4 categories. The users are domain experts and know what they're searching for. Algolia took me 45 minutes to set up and it returns results almost as fast as I can type, it was a no brainer.

However, if I had users that needed to lean on search to find things they didn't know about I would want to look into something that could infer meaning from the text input.
