Smart Search always returns the most relevant results, by performing a search of the selected product fields in four phases: (1) products with the exact phrase, (2) products with ALL keywords, correctly spelled, (3) products with ALL keywords, possibly misspelled, and (4) products with ANY keywords, possibly misspelled. Upload and go — utilizes vQmod so no core file modifications are necessary. 100% compatible with any custom theme. Choose which product fields to search within: name, description, meta tag description, meta tag keywords, tags, model, SKU, UPC, EAN, JAN, ISBN, MPN, location, manufacturer name, attribute group, attribute name, attribute value, option name, and/or option value. Automatically display search results right from the search bar with the included AJAX search functionality. Choose the default sorting for products: date added, date available, date modified, model, name, price, quantity in stock, rating, sort order, times purchased, or times viewed. Set a minimum number of results to display, so customers always have more than a few results to choose from. Optionally search for simple plurals, for misspelled words in searches, and within a category's sub-categories. Set the tolerance for misspelled words with an easy-to-use percentage scheme. Select how often to refresh the cache used for misspelled word searches: hourly, daily, weekly, monthly, or yearly. Make pre-search replacements on the search terms, such as replacing hyphens with spaces or commonly misspelled product names with correct ones. Automatically index your database tables with a single click, improving the speed of searches. Enable a testing mode to view how long queries are taking on your site.
