BooleanQuery is deprecated now.

New syntax looks like this. (should == OR, must == AND)

val searchManager = Search.getSearchManager(cache)
val queryBuilder = searchManager.buildQueryBuilderForClass(classTag[T].runtimeClass).get()
val luceneQuery = queryBuilder.bool()
luceneQuery.should(new TermQuery(new Term("type", "lala"))
luceneQuery.createQuery()

BooleanQuery mainQuery = new BooleanQuery();

TermQuery contentFilter = new TermQuery(new Term("content", "some text"));
mainQuery.add(contentFilter, BooleanClause.Occur.MUST);

BooleanQuery idFilter = new BooleanQuery();
idFilter.setMinimumNumberShouldMatch(1);
idFilter.add(new TermQuery(new Term("id", A)), BooleanClause.Occur.SHOULD);
idFilter.add(new TermQuery(new Term("id", B)), BooleanClause.Occur.SHOULD);
idFilter.add(new TermQuery(new Term("id", C)), BooleanClause.Occur.SHOULD);
mainQuery.Add(idFilter, BooleanClause.Occur.MUST);

I believe the "Grouping" section in the Query Parser Syntax documentation provides the answer:

(jakarta OR apache) AND website

I suspect you should make your operators (and, or) upper case. As well, I don't think you can use the equals operator (use a colon instead).

content:"some thext" AND (id:"A" OR id:"B" OR id:"c")
