This is because phrases are expected to contain >1 clause and the
ComplexPhraseQueryParser was expecting a BooleanQuery from the base class
which is used to hold the elements in the phrase.
In this single-clause scenario I guess we could silently hide the error and
return whatever single query clause was inappropriately found between the
quotes.
