Bing can narrow a search by exact wording, required terms, excluded terms, page location, file type, language, region, domain, and even hosting IP address. Most of the useful controls work directly in the search box, so you do not need to open an advanced-search form.
The syntax is strict in a few places: Boolean operators such as OR and NOT must be uppercase, and keyword operators cannot have a space after the colon. Use site:example.com, not site: example.com.

Boolean operators and symbols
Bing normally treats separate search terms as an AND search. For example, Windows backup encryption asks for results related to all three terms, although Bing may still vary the exact wording in its results.

Clear out junk files and repair common Windows errorsFree Scan →Scan for outdated or missing drivers - takes under a minuteDriver Scan →| Operator | Example | What it does |
|---|---|---|
| Quotation marks | "Windows 11 backup" |
Searches for the exact words in the quoted phrase. |
+ |
+PowerShell |
Requires a term and can force inclusion of words Bing would normally ignore. |
| Parentheses | (laptop notebook) |
Groups terms for inclusion or exclusion. |
AND or & |
VPN AND WireGuard |
Requires both terms or phrases. Explicit AND is usually unnecessary because Bing applies AND behavior by default. |
NOT or - |
jaguar NOT car |
Excludes a term or phrase. |
OR or | |
USB-C OR Thunderbolt |
Matches either alternative. |
Use uppercase for OR and NOT. Lowercase or and not are treated as ordinary stop words rather than Boolean operators.
#1 Best Overall
Group alternatives before combining them
OR has the lowest precedence in Bing’s documented order. Parentheses prevent the query from being interpreted more broadly than intended.
"machine learning" (site:mit.edu OR site:stanford.edu)This searches for the exact phrase on either of the two university domains. Without the parentheses, the OR can apply to more of the query than you intended.
Bing’s documented precedence order is:
- Parentheses
- Quoted phrases
NOT,-, and+ANDand&ORand|
How Bing handles punctuation and long queries
Bing generally ignores stop words and punctuation. Quotation marks preserve an exact phrase, while + can force inclusion of a word Bing might otherwise ignore. Do not assume that an unquoted punctuation mark will narrow results.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Bing uses only the first 10 terms in a query to obtain search results. A very long query can therefore lose important conditions after the tenth term. If a search is becoming complicated, split it into two searches or remove descriptive words that are not essential.
Keyword operators for focused searches
Keyword operators use the form keyword:value. The value must immediately follow the colon; a space changes the syntax.
| Operator | Example | Use |
|---|---|---|
site: |
site:learn.microsoft.com PowerShell |
Restricts results to a domain, top-level domain, or supported directory. |
intitle: |
intitle:BitLocker |
Finds the term in page-title metadata. |
inbody: |
inbody:recovery |
Finds the term in page body text. |
inanchor: |
inanchor:download |
Finds the term in page anchor text, such as a link label. |
filetype: |
filetype:pdf router manual |
Returns pages created in the specified file type. |
ext: |
reports ext:docx |
Returns pages whose filename extension matches the specified extension. |
contains: |
music contains:wma |
Finds websites containing links to the specified file type. |
language: |
"backup guide" language:en |
Limits results to a language code. |
loc: |
computer repair loc:US |
Limits results to a country or region code. |
location: |
computer repair location:GB |
An alias for loc:. |
prefer: |
football prefer:organization |
Adds emphasis to a term or another operator; it is not a guaranteed inclusion or exclusion filter. |
feed: |
feed:football |
Finds RSS or Atom feeds for the searched subject. |
hasfeed: |
site:nytimes.com hasfeed:football |
Finds pages containing an RSS or Atom feed for the subject. |
url: |
url:microsoft.com |
Checks whether a domain or web address is in Bing’s index. |
ip: |
ip:207.46.249.252 |
Finds sites hosted at a specified IPv4 address. |
Practical Bing search recipes
Search one site or a small group of sites
Use site: when you already trust a source and want to search its content rather than the entire web.
site:support.microsoft.com Windows 11 activationBing also documents grouping several sites with OR:
Windows Errors? Fix Them Before They Spread
Repair common Windows errors and clear accumulated junk for a smoother, more stable PC - no reinstall needed.Free scan · no reinstallCrashes, No Sound, or Screen Glitches?
Random freezes, missing sound and display glitches usually trace back to one bad driver. Find and replace yours safely.Free scan · under a minute"heart disease" (site:bbc.co.uk OR site:cnn.com)The documented form supports a domain, a top-level domain, or a directory no more than two directory levels deep. For example:
site:www.microsoft.com/games/pc haloFind technical documentation in PDF form
"wireless controller" filetype:pdf setupfiletype:pdf asks for pages created in PDF format. It is different from contains:pdf, which looks for websites containing links to PDF files. To find Word documents, use an extension or file type such as:
project requirements ext:docxSearch page titles and body text separately
These operators are useful when a general search produces pages that merely mention a term in navigation, tags, or unrelated metadata:
intitle:troubleshooting inbody:BluetoothOnly one term can be specified for each intitle:, inbody:, or inanchor: instance. Repeat the operator for additional terms:
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Repair Windows errors before they cause bigger problems3Fix the driver behind crashes, sound loss and screen glitchesintitle:Windows intitle:backup inbody:encryptionFor link labels, try:
inanchor:download inanchor:driver printerInclude one spelling or product name and exclude noise
(Wi-Fi OR WiFi) printer setup -advertisementYou can use NOT instead of the minus sign:
Raspberry Pi NOT recipeUse quotes when excluding a phrase:
Java tutorial NOT "JavaScript"Search for regional or language-specific information
Country and language filters use codes, not full names:
"consumer rights" language:en loc:GBYou can group several regions:
sculpture (loc:US OR loc:GB)The valid code depends on Microsoft’s country, region, and language-code list. Regional behavior and some advanced-search features can vary by country.
Find feeds
Use feed: when you want feeds about a topic rather than ordinary pages:
feed:cybersecurityUse hasfeed: to find ordinary pages that expose a feed:
site:example.com hasfeed:technologyLess common operators
Find sites by IPv4 address
The ip: operator takes a dotted-quad IPv4 address:
ip:207.46.249.252Use four decimal components separated by dots. The documented syntax does not specify hostnames, CIDR ranges, or other address formats as valid alternatives.
Check whether a URL is indexed
url:example.comThis checks whether the domain or web address is in Bing’s index. It is an index check, not a guarantee that every page on the site is indexed.
Use preference without treating it as a hard filter
football prefer:organizationprefer: adds emphasis. Unlike site:, filetype:, or NOT, it does not impose a strict boundary, so results may still include pages that do not match the preferred term exactly.
Chaining operators without making the query brittle
Several metadata operators can be combined in one query:
Free tools Windows power users keep installed
One-click scans. No signup required.
inanchor:msn inbody:spaces inbody:magogA more practical technical example is:
site:docs.example.com intitle:API inbody:authentication filetype:pdfBuild complicated queries in stages:
- Start with the subject:
authentication API. - Restrict the source:
site:docs.example.com authentication API. - Add a format:
site:docs.example.com authentication API filetype:pdf. - Add title or body conditions only if the result set is still too broad.
- If alternatives are needed, group them with parentheses:
site:docs.example.com (OAuth OR SAML).
This approach makes failures easier to diagnose. If adding an operator suddenly removes useful results, delete only the last condition and test it separately.
Common mistakes and failure modes
| Mistake | Incorrect | Correct |
|---|---|---|
| Space after a keyword colon | site: example.com |
site:example.com |
| Lowercase Boolean keyword | laptop or tablet |
laptop OR tablet |
| Assuming punctuation is significant | Wi-Fi when the hyphen is essential |
"Wi-Fi" or an appropriate + term |
| Putting multiple terms after a metadata operator | intitle:wireless router |
intitle:wireless intitle:router |
| Writing an oversized query | A sentence containing many conditions | Keep essential terms within the first 10 query terms and split complex searches |
Expecting prefer: to enforce a rule |
prefer:official as a strict source filter |
Use site: or another hard restriction when precision matters |
Microsoft’s documentation also notes that some advanced-search features may not be available in every country or region. Results can change with Bing’s index, language, location, and ranking systems, so an operator should be treated as a way to narrow the search—not as a promise that every matching page will appear.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.A compact workflow for everyday research
- Put an exact product name, error message, or quoted sentence in quotation marks.
- Add the most important technical term. Do not write
ANDbetween every word unless it improves readability. - Use
site:for vendor documentation, a government site, a university, or another trusted source. - Use
NOTor-to remove a common but irrelevant meaning. - Use
filetype:orext:when the document format matters. - Use parentheses around alternatives joined by
OR. - Remove unnecessary words if the query approaches 10 terms.
For example, troubleshooting a printer driver could progress from:
printer driver not installingto:
"printer driver" installation site:support.example.comand then, if a manual is needed:
site:support.example.com "printer driver" filetype:pdfFAQ
Does Bing require AND between every search term?
No. Bing uses AND behavior by default, so separate terms are normally treated as required terms. Explicit AND or & is available but usually unnecessary.
The Tool Desk
Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →Why does Bing ignore lowercase “or” or “not”?
Microsoft documents OR and NOT as uppercase Boolean operators. Lowercase forms are treated as stop words, so use uppercase.
Best Value
- Used Book in Good Condition
What is the difference between filetype:, ext:, and contains:?
filetype: returns pages created in a specified file type. ext: matches the filename extension. contains: finds websites containing links to the specified file type.
Can I put several words after intitle: or inbody:?
Use one term per operator instance. For multiple terms, repeat the operator, such as intitle:Windows intitle:backup.
Why did my long Bing query ignore part of my request?
Bing uses only the first 10 terms in a query to obtain search results. Shorten the query or run it as two separate searches.
Can I use a hostname with ip:?
The documented ip: syntax requires an IPv4 dotted-quad address, such as ip:207.46.249.252. Microsoft does not document hostnames or CIDR notation for this operator.
The Bottom Line
The most dependable Bing controls are "exact phrases", +, NOT/-, grouped OR alternatives, and source or format restrictions such as site: and filetype:. Keep Boolean words uppercase, leave no space after an operator colon, repeat metadata operators for additional terms, and avoid queries longer than 10 terms. For the complete current syntax, see Microsoft’s Boolean and symbol operator documentation and advanced keyword reference.
