You can make search query with more than one entry. Would you like to find all files from a production number and from the location you can do that. You find the production number 92342 and the location London and type or copy them into the search field.
Then you will see all the files that have these two values.
You can select any file and ioGates will open it in the player window. Use the Toggle to come back to the search window to select a other file, this way you do not need to make a new search if the first you selected was not the right one.
