Is there a way to specify a search whose results list is the union of two other searches?
1 Answer
You can do OR
searches on tags. For example, [linear-algebra] [or] [real-analysis]
returns questions tagged with at least one of the two tags.
It doesn't look like the search engine here supports the OR
operator for text keywords. You can use Google for this:
convergence OR matrix site:math.stackexchange.com
