Note that the last term here is: title:Xapian is good

Here you have the term: titleXapain is good

Your first problem is that "Xapian" is misspelled as "Xapain" here,
but not above.

Your second problem is that there's no colon in this term, but there is
above.  It looks like you've told QueryParser to use the prefix "title:"
but TermGenerator to use the prefix "title".  You need to be consistent
about this (and I'd recommend a colon or some other separator, as
otherwise it can be ambiguous where the prefix ends and the term begins,
especially with a lower-case prefix like you're using).
