to open the Search page. You can set the search filters to narrow or broaden your search.
The following search rules apply when searching the Help:
• Boolean—All search words and phrases have an implicit AND.
• Wildcard Search—All search words have an implicit wildcard. For example, if you type extr, your search results will include any string that starts with extr, such as extrude and extra.
• Word Search—For example, a search for round feature finds all Help topics containing both round and feature. The terms do not have to be next to each other.
• Phrase Search—To find an exact phrase, enclose the phrase in quotations. For example, search for “reference model” to find all Help topics containing the exact phrase reference model.
