Thanks to Algolia, I integrated a search system in my project made with Angular / Fire. Now I am thinking of integrating its geo-search. Hopefully, it will be as good as your search with firestore.

The best of all is the ease of integration with your project, both to the back and front, and how easy it is to build the queries.

That it does not have a pay per use as firebase does, you only have 2 options, the free account or the payment commitment, use or do not use all your operations for which you are going to pay

Overall experience has been regular. In general we needed around 2 months with 2 experienced wordpress developers to be able to implement Algolia which now works ok.

The clear analytics and ease to separate accounts when using multiple of them, however this comes at a high cost.

The difficulty to implement with wordpress. The high cost. The lack of flexibility when integrating with other sistems that algolia does not come out of the box for.

The algorithm can be quite good, but you need to twist te right knobs to get that result. This also goes for the implementation.

Algolia is a tool that comes with a lot of features. However, it's not as easy to implement as you would think.

It was not "plug and play". The implementation is integrated in the website and you need to work on the interface before you can implement it correctly.

The documentation is very well organized and so it was easy for us as a startup to add search functionality to our product. There is an official python client package, including packages for other languages.

It's a bit expensive so we'll have to evaluate at the time we want to scale.
