welcome to Accordance. I hope we can help you!
As to your question, it depends on what you mean exactly. If you just want to display 2 texts side by side, that's pretty simple.
When you first open Accordance, you will probably have a single workspace with a single tab in it (depending on how you set it up). If you open a new tab (CMD-N) you will get a second tab with your default text.
if you then click and hold the second tab, you can drag it to the right (a sort of ghost image will appear and show you where it will appear) and then let the button go. You will have that second tab now in a new zone which is independent to the first one and you can put different searches in each one - even different resources if you wish. If you have 2 texts open and you tie them together they will no longer be able to be independent to each other (ie they will attempt to display the same verses) and you cannot use the "compare text" button, as this only works in parallel panes in the same language with the same pericope.
Here are some screenshots of how to do it.
