Google Search Appliance: Search Protocol Reference Request Format 23

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

indexed as two separate words,

802.11

and

Note: An underscore (or under bar) is not a query term separator. For example, if you search for

taino_the_parrot

, the only valid search result is a document that contains the exact phrase,

taino_the_parrot

. A search for

taino

parrot

does not return the

taino_the_parrot

result.

Special Query Terms

Google search supports the following special query terms. A user or search administrator can use these

terms to access additional search features.

Note: All query terms must be correctly URL-encoded in a search request (see “Appendix B: URL

Encoding” on page 107).

Anchor text search

Restricts the search to pages that contain all the search terms that are specified in the anchor text in

links to the page. For example,

allinanchor:best museums sydney

returns only pages in which the

anchor text in links to the pages contain the words “best,” “museums,” and “sydney.” The following

example shows an anchor tag:

<a href="http://foo.com"> museums </a>

allinanchor:

evaluates the text between

and

</a>

allinanchor:

evaluates only

<a href

anchor

tags. It does not evaluate

<a name

anchor tags.

An anchor is a marker inserted at a specific section of a page. It lets the writer of the document create

links to these anchors, which, when clicked, quickly take the reader to the specified section of the same

page or another page. The table of contents at the top of this document, for example, uses hyperlinks

to anchors embedded throughout this document.

Do not include any other search operators with the

allinanchor:

operator.

Sample usage:

allinanchor:membership directory

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. A

hyphen after a parenthesis is treated as the Exclude Query Term

operator. For example, the query

Fmoc-Cys(Trt)-OH

returns documents

that contain

Fmoc-Cys(Trt)

and excludes documents that contain

addition to

Fmoc-Cys(Trt)

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.
