示例1: search
import org.apache.lucene.facet.range.LongRange; //导入依赖的package包/类
/** User runs a query and counts facets. */
public List<FacetResult> search() throws IOException {
RangeFacetRequest<LongRange> rangeFacetRequest = new RangeFacetRequest<LongRange>("timestamp",
new LongRange("Past hour", nowSec-3600, true, nowSec, true),
new LongRange("Past six hours", nowSec-6*3600, true, nowSec, true),
new LongRange("Past day", nowSec-24*3600, true, nowSec, true));
// Aggregatses the facet counts
FacetsCollector fc = FacetsCollector.create(new RangeAccumulator(rangeFacetRequest));
// MatchAllDocsQuery is for "browsing" (counts facets
// for all non-deleted docs in the index); normally
// you'd use a "normal" query, and use MultiCollector to
// wrap collecting the "normal" hits and also facets:
searcher.search(new MatchAllDocsQuery(), fc);
// Retrieve results
return fc.getFacetResults();
}

示例3: drillDown
