Thanks. What eddect does this have on the quality of the returned matches? Are there any guidelines as to when you would disable field norms, and on which type of fields?
For position increment gap, have a look at http://lucene.apache.org/java/docs/api/org/apache/lucene/analysis/Token.html#setPositionIncrement(int) , it is described pretty well there.
Right - so whereas in most cases it is set to 100, in fact a number of 5 or so would be plenty, is that correct? In fact, isn't it more-ore-less a boolean switch?
