Module adds 'language' to the search SQL query.

README

A fix for the localization lack of the search results.

Search module doesn\'t return localized search results, logically, as it is a side wide result.
However, in some cases we only want to see the localized results, therefore this module adds the language argument to the SQL query.

This is what you should do:

- Copy this module into your "../modules/custom" folder
- Activate the module
- And that's it, all the rest is handled by this piece of code!

And remember Confucius Says: "Never approach a bull from the front, a horse from the rear or a fool from any direction".
