CFCOLLECTION CFSEARCH CFINDEX 2023

Hello I am new to Cold Fusion,

        Well I am new to Cold Fusion 2023. The last Cold Fusion version I have used is CF 10.

We have a web site that I would like to migrate to Cold Fusion 2023 and it is basically a document search web site. I need to know if the 2023 version has the same functionality for collections and search as in the past. I know that Adobe has replaced Verity with SOLR. Any major differences in setuping the collections, indexing and searching them?

     Is there is anyway I can move the current web site to testing/development environment to do the testing until we decide on investing in the new Cold Fusion Server? The testing environment should also have SQL server.

Thank you so much!
