BooleanQuery can be nested, so you do a top-level BQ that has two clauses,
the first a TQ for a:x and the second another BQ that itself has two

Hi Lan,
Thanks for your Reply.
I am doing similar to this only..In MultiPhraseQuery object actual phrase
is going proper but it is not returning any hits..
In Lucene 3.6,I implemented the same logic and it is working.
In Lucene 4.3,I implemented the Index for that using
FieldType offsetsType
I use the code below to do something like this. Not exactly what you
want but should be easy to adapt.
public List findTerms(IndexReader _reader,
String _field) throws IOException {
List l = new ArrayList();
Fields ff = MultiFields.getFields(_reader);

Hi,
The behavior is expected with stemming.
Have you tried using StandardAnalyzer which do not do stemming?

it doesn't lower-case the tokens though. Depending upon your
