IIRC the space character of a property value must be escaped (%20)
because Org uses the plain space character to separate multiple values
in a property. So the drawer should look like:
:PROPERTIES:
:TITLE: Quantum%20Mechanics
:AUTHOR: Franz%20Schwabl
:CATEGORY: Quantum%20Mechanics
:TAGS: Quantum%20Mechanics Group%20Theory
:KEYWORD: Quantum%20Mechanics Perturbation Second%20Quantization
:LOCATION: iTune
:END:
But now, sadly, that's all we've got. The search engine can only
search for equal strings (e.g. TITLE="Quantum%20Mechanics") or regular
expression and it does not handle multivalue properties.
Looks like to use the intended functionality someone has to patch Org
mode's tag search to handle multivalue properties.
Best,
