Examples of org.apache.lucene.queries.ChainedFilter

org.apache.lucene.queries.ChainedFilter

Allows multiple {@link Filter}s to be chained. Logical operations such as NOT and XOR are applied between filters. One operation can be used for all filters, or a specific operation can be declared for each filter.

Order in which filters are called depends on the position of the filter in the chain. It's probably more efficient to place the most restrictive filters /least computationally-intensive filters first.

        Filter filter;
        if (spatialfilter == null) {
            filter = duplicateRemovingFilter;
        } else {
            Filter[] filters = new Filter[]{duplicateRemovingFilter, spatialfilter};
            filter = new ChainedFilter(filters, ChainedFilter.AND);
        }


        _filter = new CachingWrapperFilter(filter);


        String sortBy = Util.getParam(request, Geonet.SearchResult.SORT_BY, Geonet.SearchResult.SortBy.RELEVANCE);
