What is the difference between PhraseQuery and BooleanQuery with BooleanClause.Occur.SHOULD

Hi,

I am using Lucene-5.0.0.
If I had a qurey "New York" and if I use the BooleanQuery with the
BooleanClause set to MUST on the two terms, is it the same as dong a
PhraseQuery with the two terms?

I am doing some 2-gram type queries and they are giving me different
results with these two methods. I am trying to understand why is the
difference.

Thank you.

Regards,
Sachin

I got the answer.
Somehow I missed it.
The PhraseQuery requires the terms to be in a fixed order whereas the
BooleanQuery does not require the terms to be
in a particular order.
