• Place in a position that implies the scope of the search (e.g., in the page header for global searching or within a tab or other defined content area for searching within a specific asset type).
• Place above the fold.

• The text labeling the button should clearly convey its function (e.g., "Search" or "Find").
• A textual button is preferred, but an iconographic treatment is acceptable if its meaning is clear (e.g., a magnifying glass or right-pointing arrow).

Pressing the “Enter” key should perform the same function as selecting the action button associated with the search box would.

• Generally allow space for three or more terms in the text box.
• Whenever possible, refer to your search logs to determine the average number of terms and/or characters to expect for typical queries.

• The default search scope should be the entire record set and should be clearly labeled as such (e.g., "Entire site" or “All products”).
• Use standard UI controls to allow the categories to be selected (e.g., radio buttons or drop-down menu).

• Links should be clearly labeled to convey their meaning (e.g., “detailed search” or “advanced search”).
• Links should be placed in close proximity to the search box.

• For example, “Search for product information” conveys to the user that search results will only return information on products, not other site content.
• When multiple query types are supported, consider indicating the types of acceptable formats (e.g., “Search by keyword or product code”).
