This is mostly for my own benefit. What it is is the URL that can be used to add a “Search Engine” in Firefox and friends preferences/settings. Possibly others as well. The GET pair udm=14 puts you at the “Web” results tab…I guess…instead of “All” which we all know is the devil. The GET pair tbs=li:1 is “Verbatim” which we all know is practically a placebo at this point. newwindow and client should be self explanatory.
