How to include form field labels in search?

Hi, is it possible to be able to search based on form field labels?
We have numerous pages with forms created by Formidable Forms. I’m attaching a screenshot of one of the pages. One example, is I’d like this page to show in the search results if someone searches for the word ‘land’. I’ve already enabled the ‘What to do with shortcodes in results content?’ option to ‘Execute them’.

Thanks.
