You can change the global and index-specific values of the all IDs threshold with the server online. The change does not take effect until the affected indexes are re-indexed or the data is re-initialized.
For example, on the command line, you can change the global all IDs threshold by running the following command:
# dsconf set-server-prop -p 20390 all-ids-threshold:2000
When you change the all IDs threshold located in the server-prop property, you must restart the server. All other all IDs threshold changes are made dynamically.
