+# Testing Search
+
+You may want to create an index that more closely resembles prod for testing search. The simplest way is to create an index that applies an english analyzer on `title` and `text` fields.
+
+### Create a new index in OpenSearch
+```bash
+curl 
+  \ -H "Content-Type: application/json" 
+  \ -X PUT 
+  \ -d '{"mappings":{"properties":{"text":{"type":"text","analyzer":"english","fields":{"keyword":{"type":"keyword","ignore_above":256}}},"title":{"type":"text","analyzer":"english","fields":{"keyword":{"type":"keyword","ignore_above":256}}}}}}' 
+  \ "http://localhost:9200/english" 
+  \ -ku admin:admin
+```
+
+### Reindex your documents into the `english` index
+```bash
+curl 
+  \ -H "Content-Type: application/json" 
+  \ -X POST 
+  \ -d '{"source":{"index":"item"},"dest":{"index":"english"}}' 
+  \ "http://localhost:9200/_reindex?wait_for_completion=false" 
+  \ -ku admin:admin
+```
+
+### Update `.env.sample`
+
+Search for `OPENSEARCH_INDEX=item` and replace it with `OPENSEARCH_INDEX=english`
