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.

Where do you plan to use it?
So far there is no built in learning to rank implementations in Lucene at
least.
There are suggestions to include those.
I do not know about Solr.
I worked on research projects on Learning to Rank algorithms and I had used
Lucene to generate the features which then I r
searched in the index that I have created?
Thank you in advance.

Yes the data is in text form with the space delimited tokens.
The queries are categories that the documents belong to.

I believe that this happens because "AND", "OR" and "NOT" are all
reserved words for joining together other search terms and therefore if
you don't want the exception thrown then you must capture any "AND",
"OR" and "NOT"s that are entered on their own and not pass them to the
QueryParser.
