UW CALS Google Custom Search Engine

Replaces the default WordPress search with Google Custom Search Engine (CSE).

UW CALS Custom Title URL

Adds a custom URL field for post or page titles, allowing you to replace their default permalinks.

Enables WordPress to include thumbnail and custom field data in its RSS2 feed.
How is works:
<ul>
<li>To retrieve post thumbnails: Add “post_thumbnail=1” to your feed’s link. (e.g. “http://www.mywpsite/feed/?post_thumb=1”)</li>
<li>To retrieve custom fields: Add “meta_keys=meta_name1[,meta_name2,meta_name3,…]” to your feed’s link (e.g. “http://www.mywpsite/feed/?meta_keys=post_quote,post_contributor” will retrieve the “post_quote” and “post_contributor” custom fields’ value, if these fields have been added to the post.)</li>
<li>To further customize your feed: use any other WP Feed options, as listed on https://codex.wordpress.org/WordPress_Feeds/.</li>
</ul>
Example: 
The http://news.cals.wisc.edu/feed/?cat=67&post_thumb=1&meta_keys=academic_info will retrieve all posts in category 67, along with their thumbnails (if available) and the value of the ‘academic_info’ field (if available).
