Tree Search for Confluence

Confluence Tree Search app is an alternative search page, which helps you to find pages you are looking for.

It organizes search results in a tree view, which allows you to find the result faster by browsing through them and choosing the one you need. Tree Search gives you a better context around search results and allows you to narrow down the search by the particular location or contributor.

Tree Search can also execute custom CQL to perform you queries in the advanced mode.

Once installed it can be easily accessed from the add-ons section in the navigation bar
