Merging a Forest
You can merge the forest data using the Admin Interface. As described in Understanding and Controlling Database Merges, merging a forest improves performance and is periodically done automatically in the background by MarkLogic Server. The Merge button allows you to explicitly merge the data for this forest.
To explicitly merge the forest, follow these steps:
Click the Forests icon on the left tree menu.
Decide which forest you want to merge.
Click the forest name, either on the tree menu or the summary page.
The Forest Configuration page appears.
Click the Merge button on the Forest Configuration page.
A confirmation message appears.
Confirm that you want to merge the forest data and click OK.
Merging data in a forest is a “hot” admin task; the changes take effect immediately.
