Matching any or all search criteria
If you are using XProtect Corporate or XProtect Expert, you can use multiple search categories in the same search. While configuring your search, specify whether your search must match any or all the search categories.
Matching all criteria gives you fewer but more accurate search results. In addition, if the search results overlap, they are combined into fewer results. See also Merged search results.
Matching any criterion gives you more but less accurate search results.
Actions that are normally available in the action bar may not be available for merged search results. This happens if the action that you are trying to perform cannot be used with one of the search categories. See also After selecting a search result, certain actions may not be available in the blue action bar.
