This plugin includes everything when it comes to search : keyword search, vector search (image and semantic), facets (filters) and sorting. It is incredibly fast and works with a wide variety of search engines (Elasticsearch, Opensearch, Algolia, Solr, Weaviate) making it the best free solution if you need a highly scalable search experience.

Don't really understand why there are not more people using this. Elastic Solr and these days Weaviate offer state of the art search which has many advantages to standard wp search. And this plugin for sure makes implementing it a lot easier. For now it offers semantic search with Weaviate, hopefully they will add semantic search to Elastic and Solr as well soon.
