QUERY TERMS
By default, Google returns
only pages that include all of your search terms. You do not need to
include "AND" between terms. The order of search terms affects
the search results. To further restrict a search, just include more
terms.
Google may ignore common words and characters such as where
and how and other digits and letters that slow down a search without
improving the results.
If a common word is essential to getting the
results you want, you can include the word by putting a plus sign (+) in
front of it. Make sure to include a space before the plus sign. For
example, to ensure that Google includes the "I" in a search for
"Star Wars Episode I", enter the search query as follows:
Star Wars Episode +I
Special Characters: Query Term
Separators
By default, non-alphanumeric characters in a search
query separate the query terms in the same way as space characters.
The following characters are exceptions:
Character
Description
Double quote mark (") Used as a special query term for phrase searches.
Plus sign (+) Treated as a Boolean AND.
Minus sign or hyphen (-) Treated as part of a query term if there is no space preceding it. A hyphen that is preceded by a space is the Exclude Query Term operator.
Decimal point (.) Treated as a query term separator unless it is part of a number (for example, 250.01).
For example dancing.parrot is equivalent to "dancing parrot" with quotes in the query. The term dancing.parrot is not equivalent to dancing parrot (without quotes).
Ampersand (&) Treated as another character in the query term in which it is included.
If a document
contains a number, with or without a decimal point, that has letters
immediately before or after it, the letters are treated as a separate word
or words. For example, the string 802.11a is indexed as two separate words,
802.11 and a.
Automatic "and" Queries
By
default, Google only returns pages that include all of your search terms.
There is no need to include "and" between terms. For example, to
search for engineering product specification documents, enter:
engineering product specifications
To broaden or restrict the
search, include fewer or more terms.
"OR"
Searches
Google supports the logical "OR" operator. To
retrieve pages that include either word A or word B, use an uppercase
"OR" between terms. For example, to search for an office in
either London or Paris, enter:
office london OR paris
See Your Search Terms in the Results
Every Google search
result lists one or more excerpts from the web page to display how your
search terms are used in context on that page. In the excerpt, your search
terms are displayed in bold text so that you can quickly determine if that
result is from a page you want to visit.
Does
Capitalization Matter?
Google searches are not case sensitive.
All letters, regardless of how you enter them, are understood as lower
case. For example, searches for "george washington,"
"George Washington," and "George washington" all
return the same results.
Refining Your Search
Since Google only returns web pages that contain all of the words in
your query, refining or narrowing your search is as simple as adding more
words to the search terms you have already entered. The refined query
returns a specific subset of the pages that were returned by your original
broad query.
Excluding Words
You can exclude a word
from your search by putting a minus sign ("-") immediately in
front of the term you want to exclude. Make sure you include a space
before the minus sign.
For example, the search:
bass
-music
will return pages about bass that do not contain the
word "music."
Phrase Searches
You can
search for phrases by adding quotation marks. Words enclosed in double
quotes ("like this") appear together in all returned documents.
Phrase searches using quotation marks are useful when searching for famous
sayings or specific names.
Certain characters serve as phrase
connectors. Phrase connectors work like quotes because they join your
search words in the same way double quotes join your search words. For
example, the search:
father-in-law
is treated as a
phrase search even though the search words are not enclosed in double
quotes. Google recognizes hyphens, slashes, periods, equal signs, and
apostrophes as phrase connectors.
