Hello,
First of all thanks for choosing our Theme, we are glad to be you in WoodMart WordPress family :-)
.
I have test your site as your search is not working fine. Kindly deactivate the third party plugins(if you have any) and then check back after clearing your site and browser cache. This will surely fix the issue.
In case if the issue is still there then remain the third party plugins as disable and share your login info. So i will check and help you out.
Best Regards.
