So what happens if you get 10M results from a search?
This seems to work. What I wish for is that sorting is
done by the search engine itself, hoping for a better
performance (and cleaner code).
And it can be done by Lucene itself...
Previously, I have created a DistanceComparatorSource
(similar to that in LIA-ch6); sorting by distance
works but relevance is lost.
Get back to using your DistanceComparatorSource, and couple that with
a SortField.FIELD_SCORE, like this:
Sort sort = new Sort(new SortField[] {new SortField("location",
new DistanceComparatorSource(<whatever args you need>)),
SortField.FIELD_SCORE});

Hi,

I like to have the results sorted by relevance +
distance, i.e., relevance first; for results of
similar relevance, order by distance. How to do
that?
How are you currently sorting? You can use
multiple sort fields
within a Sort.
