Thanks for providing this Q&A site. I think just a one or two more enhancements will make it much more useful. First, there needs to be a way to indicate that the keywords we provide must be in the results your site returns. Currently, though, you are returning content where any of the keywords are found. This usually results in getting 10,000 matches for most searches. Also, please provide a way to find articles that exclude certain keywords. Some sites do this with a minus sign. Other enhancements would be to support phrases that must appear (provided in quotes) and to show only answered questions. Thank you for your consideration.
