Hi,
But, How to calculate the coord() fraction ? I know by default,
in DefaultSimilarity the coord() fraction is defined as below:
/** Implemented as <code>overlap / maxOverlap</code>. */
public float coord(int overlap, int maxOverlap) {
return overlap / (float)maxOverlap;
}
How to get the overlap and maxOverlap value in each of the matched document(s) ?
Thanks,
Gururaja

I'm still new to Lucene, but wouldn't that be the coord()? My
understanding is that the coord() is the fraction of the boolean query
that matched a given document.
Again, I'm new, so somebody else will have to confirm or deny...
