Allows to find all posts where a particular attachment (image, video, etc.) is used.
Adds a “Used In” column to the list view in Media Library, as well as to the attachment details modal.
Finds posts that use the image (including any of its intermediate sizes) in post content, or as a featured image. Works with custom post types too.
Inspired by a <a href="http://wptavern.com/the-problem-with-image-attachments-in-wordpress" rel="nofollow ugc">WP Tavern post</a> on image attachments.

Try it live in your browser — <a href="https://playground.wordpress.net/?blueprint-url=https://raw.githubusercontent.com/1fixdotio/media-search-enhanced/master/blueprint/playground.blueprint.json" rel="nofollow ugc">launch the WordPress Playground demo</a>. Boots a WordPress instance with this plugin active and a Media Library seeded with 8 attachments, so you can see the cross-field search in action immediately. Searching <code>mountain</code> returns 6 hits (matches in filename and alt text included) — core WordPress search would only find 3.
This plugin is made for:
<ul>
<li>Search through all fields in Media Library, including: ID, title, caption, alternative text and description.</li>
<li>Search Taxonomies for Media, include the name, slug and description fields.</li>
<li>Search media file name.</li>
<li>Multi-term search — Anywhere in the WordPress admin (the Media Library list view at <code>upload.php</code>, the “Add Media” modal, and other admin screens), use commas to search for multiple items at once (e.g. <code>image-a.jpg, photo-2.jpg</code>). Matches attachments containing any of the terms. Limited to 10 terms per search. Frontend searches still treat commas as literal characters, as a query-amplification guard for public pages.</li>
<li>Use shortcode <code>[mse-search-form]</code> to insert a media search form in posts and template files. It will search for media by all fields mentioned above.</li>
</ul>
