About plugin internationalization issue

I found an issue with the internationalization of your plugin: Text domain isn’t set in plugin comment header. GlotPress, the WordPress tool for translation, needs this info to search inside your plugin and enable the strings in your plugin translation page.

You have to use your plugin slug: Text Domain: search-regex. You can read more here.

Please also note you have both a readme.txt and readme.md. Only the readme.txt is taken into account. You should to choose only one of them to avoid confusion while updates.
