+## Deactivate vector search
+
+Manually remove all embedder configuration from your index:
+
+```sh
+curl \
+  -X DELETE 'http://localhost:7700/indexes/movies/settings/embedders' \
+  -H 'Content-Type: application/json'
+```
+
+<Capsule intent="warning">
+If you don't remove all embedders, Meilisearch will continue auto-generating embeddings for you documents. This will happen even if `vectorStore` has been set to `false` and may lead to unexpected expenses when using OpenAI's paid tiers.
+</Capsule>
+
+If using Meilisearch Cloud, navigate to your project overview and find "Experimental features", then uncheck the "vector store" box.
+
+Alternatively, use [the `/experimental` route](/reference/api/experimental_features):
+
+```sh
+curl \
+  -X PATCH 'http://localhost:7700/experimental-features/' \
+  -H 'Content-Type: application/json'  \
+  --data-binary '{
+    "vectorStore": false
+  }'
+```
