Calls Shiny session's registerDataObj to create REST API. Publishes any R object as a URL endpoint that is unique to Shiny session. search_query must be a function that takes two arguments: data (the value that was passed into registerDataObj) and req (an environment that implements the Rook specification for HTTP requests). search_query will be called with these values whenever an HTTP request is made to the URL endpoint. The return value of search_query should be a list of list or a dataframe. Note that different semantic components expect specific JSON fields to be present in order to work correctly. Check components documentation for details.
