David Smiley commented on LUCENE-4373:
--------------------------------------
As part of this, I think a makeValueSource() might be modified to alter the
area similarity to consider the query shape's percentage of the bbox that it
fills. Perhaps something like this:
{code:java}
public ValueSource makeValueSource(SpatialArgs args) {
Shape shape = args.getShape();
double queryPowerFactor = 1;
if (!(shape instanceof Rectangle)) {
double queryBBoxArea = shape.getBoundingBox().getArea(ctx);
double queryArea = shape.getArea(ctx);
if (queryBBoxArea != 0)
queryPowerFactor = queryArea / queryBBoxArea;
}
return new BBoxSimilarityValueSource(
this, new AreaSimilarity(shape.getBoundingBox(), queryPower *
queryPowerFactor, targetPower));
}
{code}
> BBoxStrategy should support query shapes of any type

> Issue Type: Improvement
> Components: modules/spatial
> Reporter: David Smiley
> Priority: Minor
>
> It's great that BBoxStrategy has sophisticated shape area similarity based on
> bounding box, but I think that doesn't have to preclude having a
> non-rectangular query shape. The bbox to bbox query implemented already is
> probably pretty pretty fast as can work by numeric range queries, but I'd
> like this to be the first stage of which the 2nd is a FieldCache based
> comparison to the query shape if it's not a rectangle.
