Update 3.md #16

Closed AlaskaDave closed 8 years ago

You don't offer any guidance in deciding what sort of a test to try. Are "less than" or "more than" comparisons allowed in the query language? To leave it to the student to discover that only an equals=20 statement will work without supplying any other hints is inviting frustration.

Not yet, there's an issue out there, though: https://github.com/drolbr/Overpass-API/issues/78

I found that out because I looked it up in the Wiki. My point is that someone new to the query language may not know how to do that. To come up with an equals comparison is weird. I've done a bit of computer programming in my life and this limitation is highly unusual

I finally gave up the tutorial because I couldn't make the example using areas work . I tried every combination of operators and arrangements for those operators I could think of but with no luck. This tutorial needs to allow a student to either bypass an example or find an answer some other way because if, as in my case, you cannot get it right you're stopped in your tracks. You must quit at that step because there is no way forward.
