Once you've installed a plug-in, you don't need to worry about getting updates from the Net. Sherlock periodically checks for newer versions of your plug-ins. If it finds a newer version, you'll be asked if you want to upgrade. Sherlock is quite fast. Search results are returned very quickly, and you'll definitely save time when you use it to search multiple sites at once.
Sherlock provides a consistent interface for searching anywhere.
However, by insulating you from the search engine, Sherlock may not give you access to sites' advanced searching features. Press the Search button and Sherlock goes to work. In a moment, the search results window will appear. Click the small triangular sort arrow to reverse the list. A preview of that page appears below the hit list.
