Details

See the Search filter component page for full details about the format of queries, facet fields, and sorting options.

The Query Builder is UI agnostic and does not rely on Angular components. You can reuse it with multiple component implementations.

You can use custom widgets to populate and edit the following parts of the resulting query:

  • categories
  • query fragments that form a query expression
  • include fields
  • scope settings
  • filter queries
  • facet fields
  • range queries
constructor(queryBuilder: SearchQueryBuilderService) {

    queryBuilder.updated.subscribe(query => {
        this.queryBuilder.execute();
    });

    queryBuilder.executed.subscribe(data => {
        this.onDataLoaded(data);
    });

}

Note: From ADF 3.0.0, the query contains the "facetFormat": "V2" parameter so that all the responses have the same structure whether they come from search queries containing facetFields, facetQueries, grouped facetQueries or facetIntervals.
