I've noticed in both v2.x and v3.0.0 that searching for all instances of a node give varying results. Turns out the search-by-type doesn't find nodes if the node type contains spaces.
Step 1
Step 2 (which fails to find nodes if the name contains a space)
Step 3 - Removing type: form the search phrase will find all instances, though it would be nice if spaces were supported in the type: search param.

Annuello.
