How do you disable default search suggestions from Magento?

Method 1:

Comment out the following line in /template/catalogsearch/form.mini.phtml:

searchForm.initAutocomplete(...

Method 2:

Add the following code to app/design/frontend/YOUR-PACKAGE/YOUR-THEME/template/tagalys/all_pages.phtml. If the file doesn't exist in that location, create it.

<style>

.search-autocomplete { display: none; }

</style>
