Global search is slow. Search latency sits at ~30 seconds. Historically, identical queries completed within 1–4 seconds. Root cause unclear, maybe hardware problems.

Performance appears to have returned to normal without code changes.

• [ ] Compare CD with prod wrt latency. See if hardware is really the problem.
• [ ] Check out query plans and execution paths for global search (xapian delve, fall-back sql, weaved in gnqna)
• [ ] Doc performance.
