Diagnose a problem There the multiple possible reasons for search performance degradation. The most common ones are: Memory pressure: if the working set exceeds available RAM Complex requests (e.g. high , complex filters without payload index) Competing background processes (e.g. optimizer still running after bulk upload) Problem with the cluster (e.g. network issues, hardware degradation) Single Query Too Slow (Latency) Use when: individual queries take too long regardless of load. Diagnostic steps: - Check if second run of the same request is significantly faster (indicates memory pressure)…
