+### Vector Search
+
+**Vector search** finds the most similar frames to a specific reference vector. Frames are evaluated based on vector 
+embeddings that have been registered to them through the SDK.
+
+To find the frames most similar to one of the frames in the version: 
+1. Hover over the desired frame
+1. Click <img src="/docs/latest/icons/ico-dots-v-menu.svg" alt="Dot menu" className="icon size-md space-sm" />

+1. Under **Vector search**, enter the vector values under **Reference vector**.
+1. Input the [search configuration](#search-configuration)
+
+#### Search Configuration
+* **Vector field** - Select the FrameGroup's vector field that will be compared against the reference vector.
+* **Number of neighbors** - Choose how many nearest neighbors to show.
+* **Search strategy** - Either of:
+  * `KNN` (K-nearest neighbors) 
+  * `HNSW` (Hierarchical Navigable Small World) - Available with cosine similarity only.
+* **Similarity function** - Select `Cosine similarity`, `Euclidean distance`, or `Dot product`. 
+
+After entering the search configuration, click **Apply**.
+
+The frames are returned in order of their similarity to the reference vector. The calculated similarity is displayed on 
+each frame preview:

+Vector search results adhere to configured frame filters. For example, if you filter for frames containing the ROI label
+`cat`, the search will return only the nearest neighbors among frames with that ROI.
