Adding Typesense to the list as an easier-to-use alternative to ElasticSearch: https://github.com/typesense/typesense

One thing to point out though is that Typesense, MeiliSearch (and Algolia) are designed for Instant Search experiences, and so hold the entire index in memory. So for petabyte scale data (like logs) it might be wasteful (and expensive) to store that size of data in memory. This is where ElasticSearch shines and of course comes with it the overhead of managing it.
