You can read more about search engine here:

 
https://www.ovirt.org/documentation/admin-guide/appe-Using_Search_Bookmarks_and_Tags/

So if you have for example following VMs in system:

  vm
  vm1
  vm2
  vm3

And you do search like:

   api/vms?search=name=vm

It will return only single Vm called 'vm', but it always return a 
collection, but with just single item.

And you do search like:

  api/vms?search=name=vm*

It will return all VMs starting on 'vm' string. So it's collection of 
vm, vm1, vm2 and vm3.

So by default it search for exact string, but you may use wildcards to
improve the search.
