TIPS:
This search tool uses key words from how the patches are titled on the website but without the commas.
It is best to try and limit words you use to as few a possible as it will only search for the words as they are titled. I would only try and use one word for your search such as a city name only, to bring up everything with that name in the title.
For example: searching for gilbert will find all patches with gilbert in their title.
Be aware that when the pictures appear the title might start with the word wish which tells you its in my wish list or it may start with the words trade list which tells you it is on my trade list etc.
