Solo theme: remove or edit search

I’m making some edits to the Solo theme to use for a personal portfolio site. I’d like to either remove the search button on the navigation, or simply change the helper text which currently reads “search posts, tags and authors”. Any ideas?

You can’t edit the text that appears in the search overlay, but if you want to remove the search button from the header you can add the following in code injection:

<style>button.gh-search { display: none; }</style>
