I would recommend to use TermsFilter (http://goo.gl/BC9eQ, possibly wrapped
by a ConstantScoreQuery). You must do the query building by hand, yuery
*parser* cannot do that:
TermsFilter tf = new TermsFilter(); // it is in lucene-queries.jar
tf.addTerm(new Term("id", val1));
tf.addTerm(new Term("id", val2));
tf.addTerm(new Term("id", val3));
tf.addTerm(new Term("id", val4));
// if you need a query and don't want to use a Filter:
Query wrappedQ = new ConstantScoreQuery(tf);
You can execute the Filter as addon to your already prepared query:
searcher.search(queryParser.parse("content: (hello world)"), filter,...);
Or you use the wrapped as ConstantScore and combine it with the query:
BooleanQuery bq = new BooleanQuery();
bq.add(queryParser.parse("content: (hello world)"),
BooleanClause.Occur.MUST);
bq.add(wrapped, BooleanClause.Occur.MUST);
searcher.search(bq,...);
