I'm trying to work with Riak on PHP. I read the documentation but no luck. So I've already configured the "search" option in /etc/init.d/app.conf as true. So, print_r($results) returns as null array.
# Connect to Riak
$client = new RiakClient('127.0.0.1', 8098);
$bucket = $client->bucket("searchbucket");
$bucket->newObject("one", array("foo"=>"one", "bar"=>"red"))->store();
$bucket->newObject("two", array("foo"=>"two", "bar"=>"green"))->store();
# Execute a search for all objects with matching properties
$results = $client->search("searchbucket", "foo:one OR foo:two")->run();
print_r($results);
What is wrong with my code? What I misunderstood?
