TermQuery and TermRangeQuery


A TermQuery is a very simple query that matches documents containing a specific term. The TermRangeQuery is, as its name implies, a term range with a lower and upper boundary for matching.

How to do it..

Here are a couple of examples on TermQuery and TermRangeQuery:

query = new TermQuery(new Term("content", "humpty"));
query = new TermRangeQuery("content", new BytesRef("a"), new BytesRef("c"), true, true);

The first line is a simple query that matches the term humpty in the content field. The second line is a range query matching documents with the content that's sorted within a and c.
