query parser does one pass looking for operators, it sees two pieces of
input: "hello" and "world" it hands each individually to your analyzer.
for each word, your analyzer produces multiple tokens -- which are not at
the same position (they have non zero positionIncrimentGap) QueryParser
sees the multiple tokens at consecutive positions, and constructs a phrase
query (per word). if there was at least one token with a
positionIncriment of 0, it would have created a MultiPhraseQuery (per
word), if all had 0 positionIncriments, it would have constructed a
BooleanQuery (per word) containing TermQueries.
