1.7. Advanced Search
Google's default simple search allows you to do
quite a bit, but not everything. Google's Advanced Search page (http://www.google.com/advanced_search?hl=en),
shown in Figure 1-1, provides more options, such as
date search and filtering, with "fill in the
blank" searching options for those who
don't take naturally to memorizing special syntax.
Figure 1-1. Google's Advanced Search page
we'll take a quick look at the kinds of searches
that would be more difficult using the single-text-field interface of
a simple search.
1.7.1. Query Words
Because Google uses Boolean AND by
default, it's sometimes
hard to logically build out the nuances of a particular query. Using
the text boxes at the top of the Advanced Search page, you can
specify words that must appearexact
phrases, lists of words, at least one of which must appearand
words to be excluded.
1.7.2. Language
Using the Language pull-down menu, you can specify what
language all returned pages must be in,
from Arabic to Turkish.
1.7.3. File Format
The File Format option lets you include or exclude several
different file formats, including
Microsoft Word and Excel. There are a couple of Adobe formats (most
notably PDF) and Rich Text Format as options here, too. This is where
the Advanced Search is at its most limited; there are literally
dozens of file formats that Google can search for, and this set of
options represents only a small subset. To get at the others, use the
filetype: special syntax described earlier in
"Special Syntax."
1.7.4. Date
Date allows you to specify search results updated in the last three
months, six months, or year. This date search is much more limited
than the daterange: special syntax, which can give
you results as narrow as one day, but Google stands behind the
results generated using the Date option on the Advanced Search, while
not officially sanctioning the use of the
daterange: search.
1.7.5. Occurrences
Using the Occurrences pull-down menu, you can specify where the terms should
occur. The options here, other than the default, generally reflect
the allin*: syntax elementsin the title
(allintitle:), text
(allintext:), URL (allinurl:),
and link anchors (allinanchor:) of the page.
1.7.6. Domain
The Domain feature is an interface to the
site: syntax.
It also allows negation, explained earlier, to explicitly
not return results from a site or
domain.
1.7.7. Safe Search
Google's Advanced Search further gives you the
option to filter your results using SafeSearch. SafeSearch only filters
sexually explicit content (as opposed to some filtering systems that
filter pornography, hate material, gambling information, etc.).
Please remember that machine filtering isn't 100%
perfect.
1.7.8. Additional Google Properties
The rest of the
page provides
individual search forms for other Google properties, including a news
search, a page-specific search, and links to some of
Google's topic-specific searches. The news search
and other topic-specific searches work independently of the main
Advanced Search form at the top of the page.The Advanced Search page is handy when you need to use its unique
features or you need some help in putting together a complicated
query. Its "fill-in-the-blank"
interface will come in handy for the occasional searcher or someone
who wants to get an advanced search exactly right. That said, it is
limiting in other ways; it's difficult to use mixed
syntax or build a single syntax search using OR.
For example, there's no way to search for
site:edu OR
site:org using the Advanced Search. This search
must be done from the Google search box.Of course, there's another way you can alter the
search results that Google gives you, and it doesn't
involve the basic search input or the Advanced Search page.
It's the preferences page, described in
"Setting Preferences," later in
this chapter.
