Cyba Advanced Search

Creates a search page where you can use a search filter to go over a selection of your posts to search by multiple categories and tags.

• You should have 2 parent categories with sub categories in both.
• You should also set up some post tags. This will help you to really make full use of the plugin.
• In your WordPress dashboard, go into Settings -> Cyba Advanced Search to choose your options. Use the shortcode: [cyba-advanced-search] on any page to show the plugin in action.

I definitely plan to develop this plugin further.
