It's worth noting that Manticore search isn't a new development: it's a fork Sphinx, a pretty popular search engine in 2010s written by Andrei Aksenov in C++. It got superceded by ElasticSearch because the original engine never fully emraced multicore processing and working as a cluster, but I personally used Sphinx and it was very simple and very robust, a stark contrast to Elasticsearch, especially for tasks where you do need to ingest a lot of data like log collection.
