If you're using Firefox, there's probably a search box on your toolbars. If you're like me, it's usually set to Yahoogle, but every now and then it's handy to search BlueNC. And the search function here is, howyousay, less than robust.
Right-click on the following link and select "Save Link As..." and put the file somewhere handy on your computer, maybe the desktop.
Then you'll need to copy and paste the file into the "searchplugins" folder in your profile folder. Here's where that is on my computer: C:\Documents and Settings\Username\Application Data\Mozilla\Firefox\Profiles\junkjunk.default\searchplugins\ . The stuff in italics may be different for you. If you're the only user on your computer, the Username may be "Administrator." Note that you won't see the "Application Data" folder unless you have hidden files and folders turned on. If you get to that point and can't see the folder, just click "Tools" in the menu, then "Folder Options...," then the "View" tab, then click "Show hidden files and folders" and "OK."
Let me know if you have any problems!
