Hi Carl,

> Whats the best approach for excluding documents from a view based on a =
list of regex expressions. For example I want to exclude anything where =
doc.issue.name contains a value that matches a list of regex =
expressions.
> e.g. exclusion list: [/foo/, /bar/]

I am not sure what is the best approach to do that.

For your example, you could have done:

function(o) {
  switch (o.issue.name) {
      case "foo":
      case "bar": break;
      default: emit(o.issue.name, null)=20
    }
}

The pros is that you can add other exclude values very easily.  But it =
only works with strings. If you need real regexes, I suppose you will =
need to build one huge regex containing them all.=20
