Direct use of natural language search: in Windows 7 systems, open Explorer and click the Organize-> folder and search option.
Switch to the Search tab and check the "Use natural language search" item.
Now, enter multiple query keywords in the start search box or in the search box in the top right-hand corner of the explorer. For example: small easy and *.txt or IE9
The "or" here is a natural language that represents the meaning of the connector "or". Similarly, the common natural language also has "and", which means the meaning of the connector "and".
Windows Vista System
Windows Vista does not support natural language search. But it doesn't matter, we can use the syntax keyword for multiple conditional searches (the same applies to the Windows 7 system for syntax-keyword multiple-condition search).
In the Windows 7/vista system, enter the search criteria keyword directly in the search box in the Start search box or in the upper-right corner of the explorer, and then use the "Space + grammar keyword + space" in the middle of the keyword to separate it. For example, to search the above file, enter the small easy and *.txt OR IE9, the search results will automatically pop up.
Small tip: Windows 7/vista syntax keywords such as OR, and English must be capitalized.
Windows XP System
Just double-click "My Computer" and click the "Search" button above or click "Start" to-> "search".
Select a search file type.
Enter search file name, when searching multiple files, the middle of the file is separated by "comma", for example, IE9.
Note:
Test environment: Windows 7 System.
