Return Partial Results From Event Frame Search in PI Web API
Currently when searching for event frames, a 400 error is returned if not all elements in the search exist.
This is cumbersome especially in the case of asset swapping in PI Vision when parent elements could contain variable child elements. For any parent element that contains less than the max child elements, a 400 error will occur when searching for event frames for related parent elements.

To be more general:
This is cumbersome especially in the case of loading event frames for "Assets on Display" in a PI Vision display. If any symbols reference an element path that does not exist, the entire event frame search fails (even if other valid assets are present).
