There could be a number of reasons why WhoKnows is not recommending a colleague when you're doing a search.
- The most likely is that nobody within your network has expertise in that topic yet or has contacts that match the search criteria.
- WhoKnows does not recommend colleagues to help until we're certain you're looking for help, so recommendations are not always shown on your first search in a topic area. You can force recommendations by putting quotes around your topics. This will do a direct match against your colleagues' profiles and find matches.
