示例1: BoostedCaseInsensitivePhrase
public void BoostedCaseInsensitivePhrase()
{
BooleanQuery originalQuery = new BooleanQuery();
Term term = new Term("_name", "value");
PhraseQuery phraseQuery = new PhraseQuery();
phraseQuery.SetSlop(2);
phraseQuery.Add(term);
phraseQuery.SetBoost(10);
originalQuery.Add(phraseQuery, BooleanClause.Occur.MUST);
string queryString = originalQuery.ToString();
QueryBuilder builder = new QueryBuilder();
builder.Setup(x => x.Phrase(2, 10).AddTerm("_name", "Value"));
Query replacementQuery = builder.Build();
string newQueryString = replacementQuery.ToString();
Assert.AreEqual(queryString, newQueryString);
Console.Write(queryString);
}示例2: CheckOverlap
/*
* Check if src and dest have overlapped part and if it is, create PhraseQueries and add expandQueries.
*
* ex1) src="a b", dest="c d" => no overlap
* ex2) src="a b", dest="a b c" => no overlap
* ex3) src="a b", dest="b c" => overlap; expandQueries={"a b c"}
* ex4) src="a b c", dest="b c d" => overlap; expandQueries={"a b c d"}
* ex5) src="a b c", dest="b c" => no overlap
* ex6) src="a b c", dest="b" => no overlap
* ex7) src="a a a a", dest="a a a" => overlap;
* expandQueries={"a a a a a","a a a a a a"}
* ex8) src="a b c d", dest="b c" => no overlap
