Searching in Windows 7 can be as simple as typing a few letters in the search box, but there are also advanced searching techniques that you can use. You don't have to know these techniques to search for your files, but they can be helpful depending on where you're searching and what you're searching for.
If you know which file type it is, you can just enter the file extension ("JPG" for example) in the search box. To learn more about basic searches in Windows, see Find a file or folder.
One way to refine a search is to use the operators AND, OR, and NOT. When you use these operators, you need to type them in all capital letters.
tropical AND island
Find files that contain both of the words "tropical" and "island" (even if those words are in different places in the file). In the case of a simple text search, this gives the same results as typing "tropical island."
tropical NOT island
Find files that contain the word "tropical," but not "island."
tropical OR island
Find files that contain either of the words "tropical" or "island."
Search filters are a new feature in Windows 7 that make searching for files by their properties (such as by author or by file size) much easier.
Open the folder, library, or drive that you want to search.
Click in the search box, and then click a search filter (for example, Date taken: in the Pictures library).
Click one of the available options. (For example, if you clicked Date taken:, choose a date or a date range.)
You can add multiple search filters to a search, or even mix search filters with regular search terms to further refine your search.
Depending on where you're searching, only certain search filters are available. For example, if you're searching the Documents library, you'll see different search filters than you would in the Pictures library. You can't specify which search filters you'll see, but you can change the type of file that a library is optimized for. This will, in turn, change which search filters are available when searching that library. To learn how to do this, see Customize a library.
If you want to filter on a property that doesn't appear when you click in the search box, you can use special keywords. This typically involves typing a property name followed by a colon, sometimes an operator, and then a value. The keywords aren't case sensitive.
Files whose names begin with "notes." The ~< means "begins with."
Files named "quarterly report." The = means "matches exactly."
Files whose names contain the word "pro" or the characters pro as part of another word (such as "process" or "procedure"). The ~= means "contains."
Files that aren't pictures. The <> means "is not."
Files that were modified on that date. You can also type "System.DateModified:2010" to find files changed at any time during that year.
Files whose authors don't have "herb" in their name. The ~! means "doesn't contain."
Files that are tagged with the word sunset.
Files that are less than 1 MB in size.
Files that are more than 1 MB in size.
You can use a question mark (?) as a wildcard for a single character and an asterisk (*) as a wildcard for any number of characters.
You can also use the operators AND, OR, and NOT to combine search keywords. (Note how the use of parentheses can change the effect of a search term.)
System.Author:Charlie AND Herb
Files that are authored by Charlie as well as any files that include Herb in the file name or in any file property.
System.Author:Charlie AND System.DateModified:>2009
Find only files that are authored by Charlie after 2009.
System.Author:(Charl* AND Herb)
Files that have either Charles and Herb or Charlie and Herb listed as authors.
Files that are authored by someone with exactly this name.
You can turn on Natural language search to perform searches in a simpler way, without using colons and without the need to enter AND and OR in capital letters. For example, compare these two searches:
System.Music.Artist:(Beethoven OR Mozart)
music Beethoven or Mozart
System.Kind:document System.Author:(Charlie AND Herb)
documents Charlie and Herb
Open Folder Options by clicking the Start button , clicking Control Panel, clicking Appearance and Personalization, and then clicking Folder Options.
Click the Search tab.
Select the Use natural language search check box.
Even with natural language search turned on, you can continue to use the search box in exactly the same way. If you want to use operators or search keywords, you can. The difference is that you can also enter searches using a less formal method. Here are some examples:
When you turn on natural language search, some searches might give more results than you expect. For example, if you search for "e‑mail today" you will see all messages sent today as well as any messages with the word "today" in the contents.
