I have installed a plugin from this question --> Show most recent search terms in wordpress. I have the plugin working on my site, but i would like to ask that, how to clear the recent searched keywords that displaying on my website. I am running out of idea how to make it happen.
As you can see the result from my site: www.ncc.my. There are now 10 keywords on top of search box. I want to clear all the keyword. I have searched over the google but yet to get the answer. Here is the php code of the widget. See if you can get the solution to clear the keywords. Thanks!

I can't see which part is for clearing up the keywords. Any suggestion? Thanks!
Updated part: After the clearing history issue solved, this is the next issue i got.
function get_default_options() {
return array(
'title' => '',
'max' => 4, <---it was originally set to 10
'nofollow' => true,
);
}
}
I have set the searched keywords to "4" which was originally set as 10, it should work and display only maximum 4 keywords by right. But, i don't know why the setting seems to follow the very first time i use this plugin. No matter how i tried to set from 0 to 5, the setting never take effect and the keywords there are still displaying as maximum 10 searches. Need help in this!
Any solution?
I found an "archaic" way to do it. If you search for "store" in the script", at the end of it you'll find the string
update_option( 'recent_searches_widget_data', $data );
If you set $data to 0 (e.g. $data=0;)right before this line and then you try to search something, you'll be able to delete the search history. Remember to delete the line where you set $data to 0, otherwise the plugin won't start to work again
Edit: Sorry for the late response, but I have the answers for your question (and also another way to do the previous point). What I understood is that from the script you can't change after the initialisation the number of elements that have to be shown. When does this happen? When you install the plugin. So you should unzip the folder, change the number of elements in the .php file, zip the folder and install again the plugin. Not so tricky, but quite long. Now, the good news. I don't know if you have ever managed with the database that is behind wp, but there is a table (wp_options) where many part of code that wordpress uses are stored. Usually here you can also find the data that the plugins set up. And here we go: in that table there are two rows, called recent_searches_widget and recent_searches_widget_data. In the first you can find the setting for the number of elements to be shown (its the i:10; that is set by default, if you haven't changed the script yet), in the other you can find the previous searches (and, if you want to delete them, you just need to change the value of the row to 0).
