The search includes all post types, except when searching by post content, in which case it only considers pages and posts.

In order to make search by post content work with all post types, change line 7 of searches/post_content.php

from
$sql = "SELECT ID, post_content, post_title FROM {$wpdb->posts} WHERE post_status != 'inherit' AND post_type IN ('post','page') ORDER BY ID ".$orderby;

to
$sql = "SELECT ID, post_content, post_title FROM {$wpdb->posts} WHERE post_status != 'inherit' ORDER BY ID ".$orderby;

Whow! I don’t know how many thank’s I could give!
Search Regex Plugin works fine and strong with my new WP 4.8 imported from a Joomla! I can say how many time SRP is saving for me 🙂

Since 2009 to today, my “more than 150 posts” site would be date replaced monthly, line by line.
Example: Stock empty in:(Shows actual javascript date ), normal stock in:

(date to be replaced)

With my ZERO SQL or Javascript knowledge, with your plugin it´s very easy, just 3 simple steps:
1)SEARCH PATTERN: (put info to be discovered) and REPLACE PATTERN:(put info to be replaced) , click in SEARCH;
2)After listed terms, click in REPLACE: A complete list of “BEFORE” and “AFTER” terms will appear;
3)Click in REPLACE AND SAVE: That´s it! DONE! Simple as 1,2,3!

WOW! 2 hours per month… for 8 years= 96 months x 2 = 192 hours / 24 hours( 1 day) = 8!YOU SAVED me 8 days of my life!
My heros! 🙂
Many, many thanks do develop a simple/ease to use plugin to a “dummy tech” like me!

ALthough it no longer seems to be in development, you can get a lot done with this plugin. There are a few idiosyncracies to know about though. I wrote them up here:
https://wordpress.org/support/topic/additional-usage-notes/

With the idiosyncracies fixed, or with slightly improved documentation, this plugin would easily rate 5 stars. As it is, once you get used to the workarounds, you get 5-star functionality.

Great for cleaning up post content, changing urls etc

This plugin works 10/10, I had the wrong path of images in 500 + posts, and in 1 minute I had all of theme inside the posts, loved it!
