TW Taxonomy Admin Search

What it does

- Adds a small AJAX-powered search box at the top of taxonomy metaboxes on the post edit screen.
- The search box is injected only for taxonomies that have more than 5 terms.

Install

1. Copy the folder `taxonomy-admin-search` into `wp-content/plugins/`.
2. Activate the plugin in the WordPress admin.

Notes

- The plugin adds the search UI only on `post.php` and `post-new.php` edit screens.
- AJAX responses are limited to 100 terms; adjust in the PHP file if needed.

How to test

- Create a taxonomy with >5 terms, edit a post of the post type that uses that taxonomy, and a search box should appear above the taxonomy metabox. Typing will filter the checkbox list via AJAX.
