To export the results of the current search select the "File->Export Results" menu option. The Export Results dialog allows the results to be saved either to the clipboard or to a specified file.
The results can be saved in a variety of formats including Text, Comma Separated (CSV), Tab separated, HTML and XML. For advanced formatting there is also the option of applying an XSL transform to custom format the results (sample transforms are included in the Sample Transform subfolder).
