Add support for the Meilisearch engine

[loid345]

Meilisearch is becoming the standard for search. It is one of the most promising search engines and consumes much less memory compared to elastic, has an active community and ready-made libraries for integration (https://github.com/meilisearch/meilisearch-dotnet https://www.nuget.org/packages/FluentSearchEngine/).

I suggest adding support for meilisearch
