[search] Allow spaces separating terms in OR'ed search
Feedback from an user:
I have a minor reccomendation (not important). In the explanation of the search rules with OR operator: "In order to search using a logical-OR, add search terms to the text boxes separated by a single comma." It could be useful to allow the "bar space" after the comma. I mean: "eifanfaces,fisherfaces" works well as in the example but not "eifanfaces, fisherfaces". It will be very common error in my opinion (it was my error :)). If it is not possible, you could add a warning about the use of space: "In order to search using a logical-OR, add search terms to the text boxes separated by a single comma (without bar-space between terms)." For those who read fast the instructions.
