This tool is based on UNIX shell command comm. It compares two queries and returns similarities or differences. For example, if you have two queries::
  
 a  1
 b  2
 c  3

and::

 a  1
 f  6
 h  8

Using this tool with **Lines unique to Query1** option will return::

 b  2
 c  3

If you use **Lines shared between Query1 and Query2** option output will look like this::

 a  1
