Hi,

according documentation:

**`max_num_segments`**  
**(Optional, integer) The number of segments to merge to. To fully merge indices, set it to `1`.**  
**Defaults to checking if a merge needs to execute. If so, executes it.**

Once done POST /myindex/\_forcemerge?max\_num\_segments=1, how can I reset it to default?

Thank you,  
Regards

That parameter only applies to the forcemerge you are performing, so there is nothing to change back.
