Checkmk Werk 12468: BI aggregations no longer show duplicate subtrees and nodes

ID: 12468 Title: BI aggregations no longer show duplicate subtrees and nodes Component: BI Level: 1 Class: Bug fix Version: 2.1.0i1 Some search operations for BI nodes lead to similar (but not equal) results. However, the generated aggregation nodes from these results could be identical. A new deduplication mechanism fixes this bug.
