查找长度大于 5 的文档
rockmongo 成功执行: array('$where' => 'this.name.length < 5')
php 里:$cursor = $collection->find(array('name' => array ( '$where' => 'this.name.length < 5')));
执行: localhost:27017: invalid operator: $where
改:$cursor = $collection->findAll
执行: Fatal error: Call to undefined method MongoCollection::findAll()
但 rockmongo 日志是这个 findAll 的啊
'limit' => '0',
'pagesize' => '10',
'command' => 'findAll',
)
