Examples with NormalizationH3 org.apache.lucene.search.similarities.NormalizationH3 used on opensource projects

Example 1 with NormalizationH3

use of org.apache.lucene.search.similarities.NormalizationH3 in project lucene-solr by apache.

the class TestDFRSimilarityFactory method testParameters.

/** dfr with parametrized normalization */
public void testParameters() throws Exception {
    Similarity sim = getSimilarity("text_params");
    assertEquals(DFRSimilarity.class, sim.getClass());
    DFRSimilarity dfr = (DFRSimilarity) sim;
    assertEquals(BasicModelIF.class, dfr.getBasicModel().getClass());
    assertEquals(AfterEffectB.class, dfr.getAfterEffect().getClass());
    assertEquals(NormalizationH3.class, dfr.getNormalization().getClass());
    NormalizationH3 norm = (NormalizationH3) dfr.getNormalization();
    assertEquals(900f, norm.getMu(), 0.01f);
}

Example 2 with NormalizationH3
