Currently, as of version 7.1, the Advanced Search (which is leveraged by labels, etc) uses a graphical line-based approach to scope your search, with only basic OR/AND operators and very confusing (visually) "grouping", and this makes following or adjusting the logic of a search extremely difficult and confusing.

A simple fix would be to change 'grouping' to include parenthesis on either side of each respective line item to provide visible boundaries for our constraints. Additionally, or alternatively, you could provide the summarized search logic below all of the advanced search lines to get a better idea of what the logic entails; IE: Based on the above parameters, your search is: (OS Name is Windows AND Agent Version is > 7) OR (Agent Version is = 6.5)

^^ The above would help the author of the search realize the OR is causing them to search for ALL devices running 6.5, not all Windows devices running 6.5

Anecdotal Comment: During our engagement with Quest we had four people in the room, all Engineers with scripting/programming/SQL experience, and we all came to a different conclusion for a simple 5-line search because of the placement of two OR operands and one grouping.
