[Question] Nearby filter

[sweco-semtne]

Hi,
I'm trying to understand the nearby / knn function.
Is it possible to provide a filter similar to the rbush knn filter function?

knn(tree, x, y, [k, filterFn, maxDistance])

tree: an RBush tree
x, y: query coordinates
k: number of neighbors to search for (Infinity by default)
filterFn: optional filter function; k nearest items where filterFn(item) === true will be returned.
maxDistance (optional): maximum distance between neighbors and the query coordinates (Infinity by default)

Basically I have properties on the objects and I would like the NEARBY to give me the n closest with a given property.
I'm thinking that MATCH is used after the KNN has obtained the result?

Thanks for a great product btw!

Interesting. This sounds like something that needs to be fixed and similar to #199.

I just pushed a fix to the master branch.
