Optimize Solr Index

Optimization merges all index segments into one, improving search performance and reclaiming disk space from deleted documents. This operation runs asynchronously in the background — the API returns immediately while optimization continues on the server.

Endpoint

GET https://opensolr.com/solr_manager/api/optimize

Parameters

Parameter	Status	Description
`email`	required	Your Opensolr registration email address
`api_key`	required	Your Opensolr API key
`core_name`	required	The name of the index you wish to optimize

Important:

Your index may temporarily double in size on disk during optimization
This can take a long time for large indexes
Avoid writing to the index while optimization is running
The index remains fully searchable during optimization

Response

{"status":true,"msg":"Optimization started. This runs in the background and may take a while for large indexes."}

Use the Check Optimize Status endpoint to monitor progress.
