Probem with $contains

[olivierbaudouin]

I have these requests :

{"$or":
[
{"quote":{"reference":{"$contains":["01"]}}},
{"article":{"reference":{"$contains":["01"]}}}
]
} // OK

{"$or":
[
{"quote":{"reference":{"$contains":["CR"]}}},
{"article":{"reference":{"$contains":["CR"]}}}
]
} // OK

{"$or":
[
{"quote":{"reference":{"$contains":["01","CR"]}}},
{"article":{"reference":{"$contains":["01","CR"]}}}
]
} // Not OK

This request should find lines with quote reference like "01" and article reference like "CR". It works with only "01" or only "CR", but not with both "01" and "CR" (returns nothing).

Any idea for this problem?
