How do I empty an index in an indexer cluster

[nls7010]

Clients wanted a change in how there data was displayed using the sourcetype they first used. How do I remove all of what they have currently indexed so we don't get duplicate entries?

HI @nls7010,
in an Indexer Cluster, you could:

• set to 1 the Retention Period (frozenTimePeriodInSecs = 1) for your index on Master Node,
• push configurations to Peers,
• wait 5 minutes,
• set the Retention Periodto the value you like (frozenTimePeriodInSecs = your_value) for your index on Master Node,
• push configurations to Peers.

Ciao.
