Query parser was changed to treat '-' within words as part of the word.test'.
Before that change a query 'dash-test' was parsed as 'dash AND NOTNow QP reads one word 'dash-test' which is analyzed. If the analyzer splits that to more than one token (standard analyzer does) a phrase query is created. The difference you see comes from standard analyzer which tokenizes dash-test dash-123 to tokens dash, test and dash-123. Prefix queries aren't analyzed.
So you say that dash-123 is a prefix query whereas dash-test is not? I found also (with Luke) that dash-anystring123 is not tokenized as well. What exactly are the criteria for Lucene to decide what a prefix is and what not?
Anything that ends with an asterisk is parsed as a PrefixQuery, as long as it does not have other wildcard characters. If it has other wildcard characters or the asterisk is not at the end, then it is parsed as a WildcardQuery.
