There are two different types of search boxes to choose from, either a standard search box or an advanced search box with category selection.
Each type uses advanced search and each has three options to choose from, a search box with a standard submit button, your site’s default search image button, or no button. Code is provided for each type of search box and each option. A picture of each search box is also included with the code snippet. Installation is basically deciding on where you want to place the search box and then copy and paste the code.
This contribution will allow you to place a search box, not an InfoBox, almost anywhere on your site.
