OpenSearch provides several extensions to help you refine search results and diagnose performance issues, including search result display, search result summaries, search testing, and slow query analysis and optimization.
Feature overview
Control which fields are returned in each search request by specifying default display fields in your application schema. See Search result display.
When documents are too long to display in full, configure summaries and highlighting to extract relevant snippets — helping users evaluate results at a glance. Set this up once in the console and OpenSearch automatically applies the configuration to every API query. See Search result summary.
After you upload data, test your search configuration directly in the console using the built-in Search Test page. Specify query clauses and parameters to simulate client requests before going live. See Search testing.
Slow queries — caused by excessive filter content, improper operations, or QPS spikes — drive up LCU costs. Use slow query analysis to identify high-cost queries within a time window and get optimization suggestions to bring costs down. See Query optimization.
