Example 1 with IfFunction

use of org.apache.lucene.queries.function.valuesource.IfFunction in project lucene-solr by apache.

the class TestValueSources method testIf.

public void testIf() throws Exception {
    ValueSource vs = new IfFunction(new BytesRefFieldSource("id"), // match
    new ConstValueSource(1.0f), new ConstValueSource(2.0f));
    assertHits(new FunctionQuery(vs), new float[] { 1f, 1f });
    assertAllExist(vs);
    // true just if a test value exists...
    vs = new IfFunction(new LiteralValueSource("false"), // match
    new ConstValueSource(1.0f), new ConstValueSource(2.0f));
    assertHits(new FunctionQuery(vs), new float[] { 1f, 1f });
    assertAllExist(vs);
    // false value if tests value does not exist
    vs = new IfFunction(BOGUS_FLOAT_VS, new ConstValueSource(1.0f), // match
    new ConstValueSource(2.0f));
    assertHits(new FunctionQuery(vs), new float[] { 2F, 2F });
    assertAllExist(vs);
    // final value may still not exist
    vs = new IfFunction(new BytesRefFieldSource("id"), // match
    BOGUS_FLOAT_VS, new ConstValueSource(1.0f));
    assertNoneExist(vs);
