We write our issues as user stories, of the form As a blah, I wan to blah so that blah. It'd be great if we could blacklist some of these common words so that they aren't used in matches, as, at present, the similar issues found match most often on these words.
Apologies, this affects 1.13 – not sure about 1.11.5.
It would be nice to have possibility to exclude using regexp. Since we have integrations with customers' service desks via email - that means a lot of “similar” issues just with the customer ticket ID in the summary.
