This option decides what happens when the button is pressed. The supported actions are:
Trigger live search (default)

Using only the search button to trigger the search
If you wish to use only the search button as a search trigger, then you need to disable all the other ones under the General Options -> Logics & Behaviour panel. After disabling these triggers, only the search button will activate the search process.

Visual settings - design & layout
The visual options let you change the text, alignment, colors, fonts an other button settings. Clicking on the button or the Select a button theme link, you can choose from pre-defined button themes as well.
Search button position in the filters list
By default the search button is positioned as last in the filters list. It however depends on the filters layout as well.
To change the buttons position, navigate to the Frontend Search Settings -> Advanced Menu, where you should see a drag & drop type option. On the bottom of it, you should see the search_button item. Dragging it will change it's position.
The buttons position may also be affected by the column layout. This layout can be changed on the Frontend Search Settings -> General panel.
