The plugin design:
Here is the search form with search operators. Users do not need to know or memorize drug information and can search in many ways drilling down and across specifics of each drug matching their criteria.
Each Drug has its own page. There can be many improvements here. We can display “Related Drugs”, Side effects, user reviews, dosage info etc.
The plugin comes with its own settings page. Search form can be customized; enabling/disabling form fields, making them required or optional for search etc.
Finally, the plugin activation in the plugin page.
