That's not the issue. (I've modified QP to allow "minWildcardPrefix" rather
than just on/off), but the original QP shows the problem with
setAllowLeadingWildcard(true). The compiled JavaCC code will always create a
PrefixQuery if the last character is *, regardless of any other wildcard
characters before it. Therefore the query is based on the Term:
Term(field, "*abc")
The decision is made in the JavaCC compiled code and I'm not familiar enough
with JavaCC high level stuff to know how to make it choose based on an existing
condition.
