Possibility to use a wildcard to address multiple indices in a constraint statement

[jzipfler]

I am using the bro framework to gather data and store them in the database.
Bro creates indices like "bro-201408220900".
I tried to use a star as wildcard, to restrict access to the bro related fields like that:
POST /security/constraint/
{
"authenticator" : "index",
"paths" : ["bro-*"],
"methods" : ["get", "post"],
"roles" : ["admin"]
}

Is this even possible to use such wildcards for content constraints or do I use them wrong?
