-## Lookup workspace symbol search scope and kind
+## Workspace Symbols Filtering
 
 **Issue:** https://github.com/rust-analyzer/rust-analyzer/pull/7698
 
-This request is sent from client to server to search for workspace symbols filtered by an
-optional search scope and / or an optional symbol kind.
+**Experimental Server Capability:** `{ "workspaceSymbolScopeKindFiltering": boolean }`
 
-**Method:** `workspace/symbol`
+Extends the existing `workspace/symbol` request with ability to filter symbols by broad scope and kind of symbol.
+If this capability is set, `workspace/symbol` parameter gains two new optional fields:
 
-**Request:** `WorkspaceSymbolParams`
-
-**Response:** `SymbolInformation[] | null`
 
 ```typescript
-interface lsp_ext.WorkspaceSymbolParams extends WorkspaceSymbolParams {
+interface WorkspaceSymbolParams {
+    /**
+     * Return only the symbols defined in the specified scope.
+     */
     searchScope?: WorkspaceSymbolSearchScope;
