I haven't seen it, but if someone were to set all position increments
to zero for a field, then yes it wouldn't work. Checking length
(which counts tokens) would work though:
+ if (length>0) position+=analyzer.getPositionIncrementGap (fieldName)
It is either expand Field slightly, or expand Analyzer.
Sort of... one is adding a new data member, one is behavioral.

For your need (a global increment), isn't expanding analyzer actually easier?
analyser = new OldAnalyzer() {
public int getPositionIncrementGap(String field) {
return 1000;
}
}
