Even though you did smart arrangement of website layout with menu, product module and other guideline techniques, officially research still confirm that 90% user still prefer to use keyword search for what they want immediately on your website. For Magento, easy searching means finding products easy which means a better user experience and increased sales. Moreover, products categories, search queries, static information modules and pages are all searchable and can satisfy your user until they have enough information to give a purchase decision.
How it works?
Magento Ajax Search use Ajax technologies to simplify the loading process of search quires and database loading to give almost instant search result to you website user. When they type any letter to the search box, the module instantly looks for the match results of beginning letter and call out suggested search terms and products. It automatically suggests and shows the pop-up with found products, categories and even CMS pages while one is typing in a search box.
The keyword will be getting from product title, product description, product meta tag, category name and description, all html modules or any static pages on your magento website.
The whole process is quite fast and works great even if you have a lot of products, categories and static pages.
The appearance of the pop-up is fully customizable in Magento admin configuration. You can change every element, starting from the color of keywords' highlight, backgrounds, borders, and shadow and finishing the layout of the pop-up.
