title: How can I get the nodeRef of a file in the content store?
body: <p>I need to get the nodeRef of the document knowing the file on the disk.</p>
  
  <p>Example:
  I have a file 2016/6/1/8/0/087dabc7-6b5b-4840-8f3a-d45a55735fac.bin on the disk.
  I want to get to the nodeRef of the document inside this file.</p>
  
  <p>I know the path of this file is saved in the cm:content property of the node, but I do not want to get all documents and then iterate over them until I get to right one. Is there an unexpensive way (from the performance perspective) to do this ?</p>
  
  <p>Thank you !</p>
