A powerful search would be the most important feature of any WordPress Knowledgebase/wiki/documentation website.
Helpie understands that and has a powerful search Engine with priority based search results. You can search any wiki article and the search matches title, content, and tags to return Helpdesk Articles for suggestions and search results.
As soon as you start typing a few characters, the search box shows suggestions based on title, content, and tags. You can click on the suggestions to go directly to the particular article.
If you press Enter on the search box after typing, it takes you to the Search Results page. The Search Results page shows suggestions based on title, content, and tags.
