Opensearch Support

[tiramisuliu]

I have been experimenting the query-builder package with the official Opensearch PHP client and it has been giving me promising results, so far identical to Elasticsearch!

To add more datail, I have added 2 indexes with the same mappings; 1 in Elasticsearch and 1 in Opensearch. I then indexed the same set of documents to both indexes. Finally, I was able to search for the same subset of documents, with the same search query, using the modified elasticsearch-query-builder: https://github.com/tiramisuliu/elasticsearch-query-builder/pull/1/files

Questions:

1. Would Spatie be interested in adding support for the official opensearch-php client?
   1. If so, would you like to see more rigorous testing, comparing the search result between elasticsearch and opensearch, for various cases?
   2. If not; would there be another way I can make use of this package, making search requests to opensearch?
