Example 1 with TemporalResultComparator

use of ddf.catalog.util.impl.TemporalResultComparator 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) {
