Setting up advanced search results

-
Use the default Magento search- select No to enable the advanced search by SKU, color, price, etc. You have to mark values in a list only. In case you choose Yes, the search results in Ajax Search and Autocomplete search box will be similiar with the results on Magento search page. -
Use custom collection on search controller- we recommend to select No. However if you are not satisfied with search results, you can try using a custom collection.
