Last year I had a pilot project to use ElasticSearch to power a full-text search project. I was using 7.7 at the time, on AWS ElasticSearch service.
I’ve created custom analysers as described here Language analyzers | Elasticsearch Guide [7.15] | Elastic, I’ve used filters like html_strip, and I was planning of using the Term Vectors API Term vectors API | Elasticsearch Guide [7.15] | Elastic …
Now that I’m revisiting the project, I can’t find references to any of these in the OpenSearch documentation, though if it is a 7.10 fork those features should be there. Is this an oversight in the documentation or are there differences between the projects?
In general I’m a bit worried as all the docs behind OpenSearch are focused on logs ingestion and there’s not too many examples of the text analysis capabilities. It would help me a lot make a decision on whether to base this project on OpenSearch or if I should go with an Elastic Cloud license.
