FAQ Update - Pocket Queries

More Complex Talk about AND and OR, and how to choose criteria
First, we need a lesson in computer language and logic.
While this may seem strange to bring up in pocket queries, understanding this is essential to getting exactly what you're looking for. The single biggest mistake in PQs is putting too many limiting criteria on the data, and getting no results. If you look for caches that you HAVE FOUND AND caches that you HAVEN'T FOUND, you'll get back a result of no caches. Using AND means that the individual cache must meet both criteria, and you can't have a single cache that you both have found and haven't found.
So, what do you want? Caches within 50 miles that you haven't found? Remember that there's an upper limit of 1,000 caches returned in the PQ. In densely cached areas, this might be a problem.
We're going to use a hypothetical query for the purposes of education. We're going to specifically look around my home coordinates (roughly N 41° 38.500 W 088° 13.500) and look for nearby (within 50 miles) new (placed in the last month) single stage caches that I haven't found, that also contain a Travel Bug.
|From the /Pocket page, click Create a new query and you'll have a page that looks like the image to the right.
|This is the proximity or region section. For the purposes of demonstration, we're going to do a proximity search. I'll talk about regional searches in the section on Multiple Regions.
This is one of the more complicated sections. Read the section on Attributes and PQs. For the most part, leave it blank unless you REALLY know what you're doing.
|Attributes and PQs|
The Pocket Query Generator has the ability on its page to select which attributes to INCLUDE and which attributes to EXCLUDE. But understanding how it all works is a detailed lesson in logic. For our example, we'll look at the "Dogs Allowed" attribute. Right now, there are 244 caches within 10 miles of my home.
The key point to notice is that including Dogs Allowed=NO is not the same and excluding Dogs Allowed=YES.
Back to the top.
If you're doing a search for regions instead of proximity to a set of coordinates (every cache that is in Rhode Island combined with every cache in Connecticut), you can choose the State radial button, and click the first state and scroll the little list until you find the next state. Then hold down your CTRL key and click the second state.
If you want ALL states, click the first one (Alabama) and scroll down to the last one and hold the SHIFT key to click on that one (Yukon Territory). Same thing is true for countries.
