suggestions property

List<Suggestion> suggestions

can be used to get the parsed suggestions from the results. If enablePopularSuggestions property is set to true then the popular suggestions will get appended at the bottom with a property in source object named _popular_suggestion as true.

Implementation

List<Suggestion> get suggestions {
  if (this.type != null && this.type != QueryType.search) {
    return [];
  }
  List<String> fields = getNormalizedField(this.dataField);
  if (fields.length == 0 &&
      this.results.data != null &&
      this.results.data.length > 0 &&
      this.results.data[0] != null &&
      this.results.data[0]['_source'] is Map &&
      this.results.data[0]['_source'] != null) {
    // Extract fields from _source
    fields = this.results.data[0]['_source'].keys;
  }
  if (this.enablePopularSuggestions == true) {
    // extract suggestions from popular suggestion fields too
    fields = [...fields, ...popularSuggestionFields];
  }
  return getSuggestions(
      fields, this.results.data, this.value, this.showDistinctSuggestions);
}
