Best way to index a Boolean in Lucene 4.9

Question

This question has been asked and answered previously (link below), but the answer is obsolete.

I want to use Lucene to index a document with a boolean field. The way recommended in the prior post is:

doc.add(new Field("boolean","true",Field.Store.NO,Field.Index.NOT_ANALYZED_NO_NORMS));

However, the class Field is now deprecated. What's the best way to do this today?

Which is the best choice to indexing a Boolean value in lucene?

Answer 1

This

doc.add(new Field("boolean","true",Field.Store.NO,Field.Index.NOT_ANALYZED_NO_NORMS));

simply adds a non-analyzed string field having value "true".

StringField should do the same trick these days:

doc.add(new StringField("boolean", "true", Store.NO));
