Rezerla

Rezerla Post List Field Search adds a Search in dropdown next to the search box on post list screens (<code>edit.php</code>). Search by title, content, slug, custom fields, post meta, or taxonomy — individually or across all configured fields at once.
<ul>
<li>Admin-only — no impact on front-end search</li>
<li>Per post type configuration</li>
<li>Core fields, post meta, and taxonomies</li>
<li>Optional list table columns (Show in table checkbox)</li>
<li>Temporary column and highlight when searching by a single field</li>
<li>Field discovery for meta keys and taxonomies</li>
<li>Lightweight — no frameworks or subscriptions</li>
<li>Default configuration for WP Store Locator (<code>wpsl_stores</code>)</li>
<li>No data collection or external API calls</li>
<li>Translations: English (default), Polish, German, French, Spanish, Italian</li>
</ul>
<h3>Usage example</h3>
On a WP Store Locator store list (<code>edit.php?post_type=wpsl_stores</code>):
<ol>
<li>Enter “Katowice” in the search box.</li>
<li>Select City in the dropdown.</li>
<li>Click the search button.</li>
</ol>
URL: <code>edit.php?post_type=wpsl_stores&s=Katowice&rezerla_plfs_field=city</code>
<h3>List table columns</h3>
Check Show in table in field settings to display meta or taxonomy values on the list. 
When searching by a single field, that column appears temporarily and is highlighted even without the checkbox.

Tired of typing in the same default content at the end of your post? Use the same custom fields for each new post? Make your WordPress install do it for you.
Post Content
Quickly and easily put together a block of default post text to be pulled up every time you go to write a new post. The default content box uses the wordpress visual editor – so you can add images, embed video, and style your text just as you would for a normal post. Save it, and voila – each new post gets the text.
Post Meta
You’re covered on default post meta as well – use this if your theme uses a thumbnail for each post, and you need a default if you’e got nothing to show, or if you store a little extra information in the postmeta for each post.
<h3>History</h3>
2009-04-14 v1 
Initial release
2009-05-24 v1.1 
1. Fixed problems with visual editor and Firefox which prevented posts from being saved properly, and broke kitchen sink button 
2. Plugin now removes default post meta when deactivated, so users don’t have to do it manually 
3. Changing a post meta value on the post-new.php page and hitting update no longer changes the default post meta values – only the values for that post. New posts will continue to get the values set on the admin page.
2010-01-09 v1.2 
1. Fixed Error that shows up when no default post content is set
