+## Issue: Knife search limits at 10000 records
+
+### Details
+
+The knife node list and knife node search commands are inconsistent in the number of records they return. By default, knife search returns a maximum of 10,000 records.
+
+### Fixes
+
+This issue occurs because OpenSearch, by default, limits the maximum number of records (or documents) returned in a single query to 10,000. This safeguard prevents large queries from overloading the system. This approach will do that if you try to retrieve more than 10,000 records.
+
+#### Step 1: Increase the max_result_window to retrieve more than **10000** records.
+
+In the case of embedded opensearch:
+
+```bash
+curl -XPUT "http://127.0.0.1:10144/chef/_settings" \
+    -d '{
+          "index": {
+            "max_result_window": 50000
+          }
+        }' \
+    -H "Content-Type: application/json"
+```
+
+Changes can be verified by doing the following:
+
+```bash
+curl http://127.0.0.1:10144/_settings?pretty
+```
+
+For external OpenSearch, ensure the `max_result_window` is also increased accordingly.
+
+#### Step 2: Patch the config in Automate
+
+To set the value of tracking total hits in OpenSearch, patch the following configuration in the `.toml` file.
+
+```bash
+[erchef.v1.sys.index]
+ track_total_hits = true
+```
+
+Once done, run the chef-automate config patch `</path/to/your-file.toml>` to deploy your change.
