+    public static final String MODEL_ID = "model_id";

+    /**
+     * Name of the search model id parameter. We use this key to define the id of the ML model that we will use to
+     * inference the query text during the search. If this parameter is not defined we will use the model_id instead.
+     */
+    public static final String SEARCH_MODEL_ID = "search_model_id";


Why we need 2 model_id fields? Can we only keep 1 model_id field? Why we need separate model_ids for inferencing for index and search?

It's needed to support the sparse model use case.
