Merging a Forest
You can merge forest data 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 Forests in the left tree menu. A list of forests appears.
Click your target forest.
Click the Merge button.
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.
