Example 35 with FacetsCollector

use of org.apache.lucene.facet.FacetsCollector in project lucene-solr by apache.

the class TestRangeFacetCounts method testBasicDouble.

public void testBasicDouble() throws Exception {
    Directory d = newDirectory();
    RandomIndexWriter w = new RandomIndexWriter(random(), d);
    Document doc = new Document();

    for (long l = 0; l < 100; l++) {
        field.setDoubleValue(l);
        w.addDocument(doc);
    }
    IndexReader r = w.getReader();
