Example 1 with DistanceResultComparator

use of ddf.catalog.util.impl.DistanceResultComparator in project ddf by codice.

the class QueryRunnable method getResultComparator.

protected Comparator<Result> getResultComparator(Query query) {
    Comparator<Result> sortComparator = new RelevanceResultComparator(SortOrder.DESCENDING);
    SortBy sortBy = query.getSortBy();
    if (sortBy != null && sortBy.getPropertyName() != null) {

        String sortType = sortingProp.getPropertyName();
        SortOrder sortOrder = (sortBy.getSortOrder() == null) ? SortOrder.DESCENDING : sortBy.getSortOrder();
        // Temporal searches are currently sorted by the effective time
