Description

Querqy has releases for 2.19.2 out, so lets update the page for that. There is an upcoming 3x release baking, so we'll want to update that when it's out. But lets definitely show that there is progress on the plugin by refreshing the page from the old 2.3!

@renekrie a little refresh of the page. @DmitryKey there will be a 3.x release at some point.

Thanks @kolchfa-aws for the suggestions, they all looked great. I was just showing off Querqy to someone who is looking at OpenSearch for ecommerce search use case, and having that page updated will be nice!
