Search [tag1] OR [tag2]
At the moment, the way we can filter questions by tags allows us to request either the presence of a single tag (like
[c++]), or the intersection, i.e. the simultaneous presence of all of several tags (like
[c++] [java]). That is, composition is a logical AND.
Would it be possible to also have a logical-OR operator that allows us to select the union of questions that are tagged with any one of a collection of tags, like
[c++] || [java]?
This would make it a lot more convenient to keep tabs on all questions that might be of interest.
