+# Query records older than N days efficiently
+
+## What this solves
+You often need to find records older than a threshold without loading the world into memory. This snippet:
+- Uses GlideDateTime maths to compute a date boundary
+- Uses encoded queries with index-friendly operators
+- Streams results and logs a compact summary
+
+## Where to use
+Background Script, Script Include utility, or any server-side context.
+
+## How it works
+- Compute a past date with GlideDateTime and subtract days
+- Build an encoded query like `opened_at<javascript:gs.daysAgoStart(n)` or a literal date
+- Limit fields with `addQuery` and `setLimit` when sampling
+
+## References

Subject: [PATCH 2/2] Add script to get incident records older than 30 days

This script retrieves records from the 'incident' table that are older than 30 days based on the 'opened_at' field. It limits the output to 200 records and provides a count of the retrieved records.
