Alex, Merges are only triggered by document updates, so when you start adding or changing data the system will check merge policies and decide if it should merge or not. In the meantime you can force a merge for the entire database or particular forests on the admin GUI.

I didn't notice any merging going on and I expected this to clear itself up eventually. After waiting for quite awhile (many days), it didn't do anything by itself. The merge policy for the database is: merge priority = lower, max size = 0, min size = 1024, min ration = 2, timestamp = 0 The database has three forests that are roughly balanced. As such, there is 180GB of deleted fragments. I've gone in a manually requested the forests to merge, doing them one at a time. Is there a reason why the merge didn't happen all by itself? -- --Alex Milowski "The excellence of grammar as a guide is proportional to the paucity of the inflexions, i.e. to the degree of analysis effected by the language considered."
