Hello,
Sorry to say but the Search functionality isn’t influenced by the Theme, it is the default from the WooCommerce end. So, this Search Result page isn’t editable where you can input what you want directly, unfortunately.
At the Theme level regarding the Search is an option of Full-Screen search extra content which you can find under the Theme Settings > General > Search > Full-screen search > there you can find the option: https://snipboard.io/XM4j5Q.jpg
Using this option, you can either add simple Text content or select an HTML Block that you can create under the Dashboard > HTML Blocks. In that HTML Block, you can add your choice of content to show.
To make this above options work, you need to go to the Dashboard > WoodMart > Header Builder > edit your current Header layout > and there edit the Search element > in that you need to select the Display as Full screen: https://snipboard.io/xj50qh.jpg
But remember this might not work on the Search Result page. It will show on the Full-Screen search area > when you first click on the Search icon on your Site.
Best Regards
