Run the follow to retrieve results
Get[$InstallationDirectory<>"\\AddOns\\Applications\\DocumentationSearch\\DocumentationSearch.m"];
DocumentationSearch`SearchDocumentation["test"]
The formatting I believe is stored in
C:\Program Files\Wolfram Research\Mathematica\10.0\SystemFiles\FrontEnd\StyleSheets\Wolfram\Reference.nb
Or
FileNameJoin[{$InstallationDirectory <> "\\SystemFiles\\FrontEnd\\StyleSheets\\Wolfram", "Reference.nb"}]
So run SystemOpen[""]
Editing the code you get something like the following
NotebookPut@Notebook[{},
ScreenStyleEnvironment -> "Working",
WindowMargins -> {{0, Automatic}, {Automatic, 0}},
WindowFrame -> "Normal",
DockedCells ->
FrontEndResource["FEExpressions", "HelpViewerToolbar"],
StyleDefinitions ->
FileNameJoin[{$InstallationDirectory <>
"\\SystemFiles\\FrontEnd\\StyleSheets\\Wolfram", "Reference.nb"}]
]
