Expert filter criteria deprecation (v 3.3)

The metadata-overview expert filter parameter will change a little in the future. From its previously state where it uses just basic Lucene Query language it will evolve to the Confluence Query Language (CQL). It will foremost make it easier to write custom metadata queries because the user does not need to struggle with the exact searchindex values.

To move on to CQL we added an additional Parameter "Expert filter criteria (CQL)" besides the old parameter "Expert filter criteria (Lucene)". We highly recommend to move the existing Lucene queries to CQL. To do so, please use the Atlassian CQL documentation combined with the CQL documentation of the Metadata Addon
