What are Search Targets and Search Query Input in seomatic? I am not sure this is the right place to ask this question but I really need to know it, but I couldn't ask it on the plugin's Github as this is not an issue. I am new on Craft CMS and my client need SEOmatic installed on it. I have configured everything but I couldn't understand the need of Search Targets and Search Query Input in Site Meta Section. It would be very helpful if someone helps me out for this with some real-life examples.
This has to do with Google Structured Data and how your site appears in search results. If you use these fields, your site will show a custom search box in Google Search results, like this:



Basically, the Search Target is a URL where you'd want any search queries to get directed to. So in the example above for Pinterest and a custom search for "Pizza", the Search Target might be:

pinterest.com/search?q={search_term_string}


The Search Query Input basically just tells Google what the placeholder is that you used in the Search Target. So in our example it would be:

search_term_string


I'd recommend reading this 
page from the Google Search docs in order to better understand what Search Targets and the Search Query Input are.
