There are 2 kinds of this command. One is clearing results of current page. The other is clearing results of all pages. You can access these 2 commands by the File Menu or the drop down menu right of button. Or you can click directly to clear the results of the current page.

If one page lists too many results, it will not only influence the response time of the software, but also it may be difficulty to find your interested results. If you want to software to clear the results itself, you can set the Maximum Lines in Result Page parameter in the Other Settings page. Once the number of results exceed the set value, the software will clear the result of this page automaticaly.
