Problem about parameter in NearestNeighbors.jl

I find an example from NearestNeighbors.jl package, But I can’t find the explaination to “idxs”. What does it mean? What’s more, how to get nearest neighbors and get the predicted value? The example is as follow:

using NearestNeighbors
data = rand(3, 10^4)
k = 3
point = rand(3)

kdtree = KDTree(data)
idxs, dists = knn(kdtree, point, k, true)

idxs
# 3-element Array{Int64,1}:
#  4683
#  6119
#  3278

dists
# 3-element Array{Float64,1}:
#  0.039032201026256215
#  0.04134193711411951
#  0.042974090446474184

Thank you for your answer!

It means the 4683rd column of data is closest to point, with distance 0.039. The 6119th column is second closest, and so on.

Nice！ Thanks for your help!
