This plugin provides search functionality for your WordPress installation, through Google Site Search (aka Google Custom Search). It uses Google’s XML API, and thus requires an account that has access to it (ie you need to pay for it).
The plugin hooks in to the standard WordPress search form, so there is no need to change it (standard search widgets etc will still work). The plugin provides a basic template for the search results, but you can easily make your own if you wish to customize the output.

<li>Read more about the XML API here: https://developers.google.com/custom-search/docs/xml_results</li>
</ul>
This plugin is not developed or endorsed by Google.
<h3>Customizing</h3>
If you wish to customize the search result page, create a template named ‘google-custom-search.php’ in your theme. Refer to the plugin’s ‘default-template.php’ for available template functions. The functions mimic the way that The Loop works, so it should feel familiar.
For advanced users who want even more control of the output of the plugin, it is also possible to transform the response from the XML API with an XSLT style sheet. To do this, create a file called ‘google-custom-search.xsl’ in your theme. Please refer to Google’s documentation for the XML API (https://developers.google.com/custom-search/docs/xml_results) for the format of the response.
If you have a custom search form, you need to change the name-attribute of your search field to “gcs” (ie name=”gcs”) and make sure that the form action is set to the root of your site. Otherwise the search query will not be handled by this plugin.

SearchCloak allows you to hide specific Posts and Pages from search results.
There are many reasons you may want to remove specific pages from search results:
<ul>
<li>Parent pages used to organize URLs or menus, but don’t contain actual content</li>
<li>Partial page “sections” assembled by plugins into more complete pages</li>
<li>Pay-per-click Landing Pages (You probably don’t want those showing up in search engines.)</li>
<li>Pages that present similar or duplicate content that might otherwise appear multiple times in search results</li>
</ul>
This plugin adds a “SearchCloak” option to the edit screen of Posts and Pages.
When running the Gutenberg editor, this option block will appear under the “Document” tab in the right-hand column.
The options are: 
show – Show this Page or Post in search results (default) 
cloak – Hide this Page or Post from search results 
children – Hide this Page and all its children from search results (not available on Posts since they don’t have children)
<h3>Features:</h3>
<ul>
<li>Cloaked pages are also marked as “noindex” for search engines</li>
<li>You can hide ALL the children of a given page</li>
<li>Compatible with most search plugins</li>
<li>Works with Google Custom Search</li>
<li>Admin search results DO include cloaked pages</li>
<li>Cleans up multiple “robots” meta tags in the head section (sometimes happens with multiple plugins or settings)</li>
<li>Cloaking can be enabled for custom post types in the dashboard</li>
</ul>
