I am using Lucene version 3.0.0. I am already setting boost to field but
still result are not according to requirement i.e. Document that have all
the matching term either in title or body field must be on top. Regardless
of term frequency & idf.
1. I have 2 fields in document i.e. Title & body
2. Query is: +(title: lazy^3 or dog^3 or fox^3) +(body:lazy^2 or dog^2
or fox^2).
3. Document that have all three terms in *Title* must be on top and then
all terms in titte or body and so on
I have overwrite default similarity as below but it does not work.
LoadSimilarity extends DefaultSimilarity {
private static final long serialVersionUID = -909003452363957475L;
@Override
public float coord(int overlap, int maxOverlap) {
return 1.0F;
}
