func_documentation_string: Filters the symbol nodes in the API sidebar by the given search string.
  
  Prefix `kind:` will filter by symbol kind rather than searching for the
  given text. e.g. `kind:method` or `kind:method,class`.
  
  Additionally, prefix `scope:` will filter by symbol scope rather than
  searching for the given text. e.g. `scope:inner` or `scope:static,inner`.
  @private
  
  @param {*} strSearch - String to be searched for.
