Sieve was created to solve a growing problem: white noise. As the internet grows, more and more information is in constant movement, available to the masses. This is awesome, but sometimes people just want to eliminate the excess and focus on (or eliminate) specific topics. Sieve helps you do that by filtering custom feed mashups and bringing you a customized online experience.

• -pie Remove all stories that mention "pie"
• -t:pie Remove all stories that mention "pie" in their titles
• -d:pie Remove all stories that mention "pie" in their descriptions
• -pie -cake -tea Remove all stories that mention "pie," "cake," or "tea"
• -pie -t:cake -d:tea Remove all stories that mention "pie," "cake" in their titles, or "tea" in their descriptions
• ~cake Show only stories that mention "cake"
• ~t:cake Show only stories that mention "cake" in their titles
• ~d:cake Show only stories that mention "cake" in their descriptions

Note: The ~ operator specifies that the filter is a regular expression. For example, "~cake|pie" will return stories mentioning cake or pie. If you have knowledge of regular expressions, you can make very powerful filters this way.
