Since In-Portal 5.0 we are missing Search functionality for Sections.
It's very critical to have this back since currently we converted all Categories to Sections.
I think it would be logical to have two types of searches through the section:
1. Quick/standard Search - when we only search through Data within Categories fields (Description, Keywords and so on)
2. Full-text Search - we search through the actual Content.
Let's do the 1st one for now and get more feedback and ideas (please present yours) on Full-text so we can discuss it further.
