+- An existing collection must use the space of the distance function. A collection created by another Chroma client without a space uses l2. If the space differs, creating or searching the collection throws, rather than turning the distances of another space into scores. On Chroma 1.0.0 to 1.0.5 the server does not report the space, so the check cannot be done: use Chroma 1.0.6 or later.
