The SearchPlus block is very simple use. In a nutshell, you place the block on the Search layout in the Visual Editor, and configure if required.
Open or edit the Search layout
In the Visual Editor, Grid Mode, open or edit the Search layout, found under the Archives.
If it is a new layout, you will ahve to create the other blocks, like headers and footers.
Add a SearchPlus Block
The first panel of the SearchBlock provides the usual Pizazz info and links, but also a reminder that the SearchPlus will only work when placed on the Search layout. This is simply because of how WordPress processes search results.
Set the Layout options to control the display of the search criteria selections and the search results.
Set text for labels
All the text labels that appear on the front end can be reworded as you prefer, which also enables you to localise them for your own language.
You can also format many of SearchPlus’ elements in the Visual Editor, Design Mode
