[xcode] AND [ios]

But I see 0 results when searching for the newest questions tagged with [xcode] or [ios] and score >= -2.

[xcode] OR [ios]

  • I'm not sure it's the correct syntax for an OR search. Even without the score, [xcode] or [ios] yields nothing. Also, in your screenshot, [or] looks like a tag to me. But I cannot find any documentation about the OR operator. (It seems to me that, if not recognized as an operator, or is also an ignored word, just like a, an, is, on, the, and a zillion more.) – Arjan Jan 27 '13 at 16:18
  • Ah, indeed [or] used to be the supported syntax. Not anymore, it seems? – Arjan Jan 27 '13 at 16:26
  • Is there a new supported syntax for using the advanced search features (like score: or answers:) in conjunction with [tagOne][or][tagTwo]? For now, I'm using /questions/tagged/tagOne%20or%20tagTwo, but I'd like to include advanced search features like answers:0. – John Sauer Jan 27 '13 at 17:00

    @Arjan - the [or] was never intentionally supported, and it never worked except in the explicit [tag] [or] [tag2] case, no other operators could be used. It's an artifact of how the redirect to /questions/tagged works, not the search engine...the search engine never handled it. That's not to say we won't support an "OR" tag syntax, it's on my todo after this NY move...along with 50 other items. – Nick Craver Jan 27 '13 at 18:57

Update: OR tags is now supported, it requires an explicit or between one or more tags, anything without an or in between is AND (the historical default).

For example: [xcode] or [ios] score:-2

Original answer: This is currently working as-designed, the [or] syntax was never designed to work...and it never did work when combined with anything else. It worked simply because the redirect logic never checked for it (still doesn't).

That being said "or" for tags is something I'll try and get to after our colo move to NY (hopefully this coming weekend). It's no longer technically an impossibility on the back-end, it's now just a matter of syntax and parsing.
