Sample Of Google Hacks.. Makes you think about how people will begin to search in the future to reduce false hits.

If your involved in search engines this is the book to buy.
: restricts your search to the titles of web pages. The variation,
allintitle: finds pages wherein all the words specified make up the title of the
web page. It's probably best to avoid the allintitle: variation, because it doesn't
mix well with some of the other syntaxes.
allintitle:"money supply" economics
: restricts your search to the URLs of web pages. This syntax tends to work well
for finding search and help pages, because they tend to be rather regular in composition.
An allinurl: variation finds all the words listed in a URL but doesn't mix well with
some other special syntaxes.
: searches only body text (i.e., ignores link text, URLs, and titles). There's an
allintext: variation, but again, this doesn't play well with others. While its uses are
limited, it's perfect for finding query words that might be too common in URLs or link
: searches for text in a page's link anchors. A link anchor is the descriptive
text of a link. For example, the link anchor in the HTML code <a
href="http://www.oreilly.com>O'Reilly and Associates</a>
is "O'Reilly and Associates."
: allows you to narrow your search by either a site or a top-level domain.
AltaVista, for example, has two syntaxes for this function (host: and domain
Google has only the one.
: returns a list of pages linking to the specified URL. Enter
and you'll be returned a list of pages that link to Google.
Don't worry about including the http:// bit; you don't need it, and, indeed, Google
appears to ignore it even if you do put it in. link: works just as well with "deep"
for instance—as with top-level URLs such
: finds a copy of the page that Google indexed even if that page is no longer
available at its original URL or has since changed its content completely. This is
particularly useful for pages that change often.
If Google returns a result that appears to have little to do with your query, you're almost
sure to find what you're looking for in the latest cached version of the page at Google.
: limits your search to a particular date or range of dates that a page was
indexed. It's important to note that the search is not limited to when a page was created,
but when it was indexed by Google. So a page created on February 2 and not indexed by
Google until April 11 could be found with daterange: search on April 11.
Remember also that Google reindexes pages. Whether the date range changes depends on
whether the page content changed. For example, Google indexes a page on June 1.
Google reindexes the page on August 13, but the page content hasn't changed. The date
for the purpose of searching with daterange: is still June 1.
Note that daterange: works with Julian [Hack #12], not Gregorian dates (the
calendar we use every day.) There are Gregorian/Julian converters online, but if you want
to search Google without all that nonsense, use the FaganFinder Google interface
), offering daterange: searching
via a Gregorian date pull-down menu. Some of the hacks deal with daterange:
searching without headaches, so you'll see this popping up again and again in the book.

: searches the suffixes or filename extensions. These are usually, but not
necessarily, different file types. I like to make this distinction, because searching for
filetype:htm and filetype:html will give you different result counts, even
though they're the same file type. You can even search for different page generators, such
as ASP, PHP, CGI, and so forth—presuming the site isn't hiding them behind redirection
and proxying. Google indexes several different Microsoft formats, including: PowerPoint
(PPT), Excel (XLS), and Word (DOC).

:, as you might expect, finds pages that are related to the specified page. Not
all pages are related to other pages. This is a good way to find categories of pages; a
search for related:google.com would return a variety of search engines,
including HotBot, Yahoo!, and Northern Light.
: provides a page of links to more information about a specified URL. Information
includes a link to the URL's cache, a list of pages that link to that URL, pages that are
related to that URL, and pages that contain that URL. Note that this information is
dependent on whether Google has indexed that URL or not. If Google hasn't indexed that
URL, information will obviously be more limited.
:, as you might expect, looks up phone numbers. For a deeper look, see
the section [Hack #17].
