Hi,

So you can go : to only include tags that have a certain string: name:foo (only places with foo anywhere in the name will show up), but I'm wondering if you can do the opposite, I want to EXCLUDE tags if they contain a certain word (I want every tag that does NOT contain the word foo in the example above).

I'm sure there must be a way, there's = and !=, so I'm sure they'll be some equivalent for contains, but it certainly isn't !: and I cannot find it in documentation.

Thanks in advance for your help, Steven.

Can you provide an example illustrating what you want?

I'm intrigued/confused by your first sentence. Do you have a working example to clarify what you mean?

Yes sorry, so I am wanting to see all the churches of a specific denomination, but the denomination field isn't always filled in, so I will need to do some manual filtering. I thought a way to narrow down the list though would be to exclude results that mention a denomination in it's name, so for example if it was Trinity Evangelist Church, I want to exclude all names that contain the word Evangelist.

@DaveF Sorry what I was meaning by the first sentence is that I can do the opposite, I know how to ONLY find churches that have the word Evangelist in the name, but I don't know how to EXCLUDE churches that have the word Evangelist from the results.

Sorry for the confusion.

Try with the operator "!~" which searches for values not matching a regular expression (https://wiki.openstreetmap.org/wiki/Overpass_API/Overpass_QL#Value_matches_regular_expression_.28.7E.2C_.21.7E.29); please notice that not having the tag is considered a non match, thus it's shown in the result. If you want to avoid that, just add the filter ["name"]; Example: node["amenity"="place_of_worship"]["name"]["name"!~"Evangelist"](area.searchArea);

@MarcoR Yes that worked! Thank you. If you post that as an answer, I will mark it as correct.

Try with the operator "!~" which searches for values not matching a regular expression.

Please note that not having the tag is considered a non match, thus it's shown in the result. If you want to avoid that, just add the filter ["name"].

Example:

[out:json][timeout:25];

  nwr["amenity"="place_of_worship"]["name"]["name"!~"Evangelist"]({{bbox}});

out body;
>;
out skel qt;

Another way to obtain the same result is to use the difference:

[out:json][timeout:25];

(
  nwr["amenity"="place_of_worship"]["name"]({{bbox}});
-
  nwr["amenity"="place_of_worship"]["name"~"Evangelist"]({{bbox}});
  );
out body;
>;
out skel qt;

The former should run faster but I think it depends on the area you are running it in.

Although MarcoR's former example is the preferable solution the 'difference' example, when it's the only option, can be improved slightly by passing the first call to a variable. In this example I display all edits for the last day except my own. (You'll need to add your own username)

   (
    nwr(newer:'{{date:24Hour}}')({{bbox}})->.Data;
    -
    nwr.Data(user:Joe_B);
   );
   out meta geom({{bbox}});
