# Reload search analyzer
The reload search analyzer API operation detects any changes to [synonym]({{site.url}}{{site.baseurl}}/opensearch/ux/) files for any configured [search analyzers]({{site.url}}{{site.baseurl}}/im-plugin/refresh-analyzer/index/). The reload search analyzer request needs to be run on all nodes. Additionally, the synonym token filter must be set to `true`.
