What I will cover?

4
Subset Searching

• define a group of specific domains and then
  search within that subset
• subsets can even be used for current awareness by
  combining subset search techniques with an RSS
  feed or e-mail alert.

5
Domain Limiting

• Domain limits are one of the older limits that
  search engines made available. The limit is
  typically available on the advanced search page
  as well as by command line
• site .gov
• site .il

6
Domain Limiting

• The shortest version of a domain is the most
  comprehensive
• sitestate.edu search will match pages just at
• state.edu
• www.state.edu,
• www.lib.state.edu,
• ics.chem.state.edu.

7
Yahoo! Subset Syntax

• Yahoo! can process very long search queries.
  There appears to be no obvious limit to the
  number of search terms

8
Google Syntax

• Google's search box on the main page has a
  256-character limit and a 32-word query limit.
  Using all the site operators (even using the I
  symbol rather than the OR to save characters)
  means that with about 16 sites

9
Expanding searching to subset

• Gigablast is the only one that handles
• multiple sites well and looks for results in
• any of the domains put in its "Restrict to
• these sites" box.

10
GIGABLAST CUSTOM TOPIC SEARCH

• The advanced search form has a box that will
  accept up to 200 sites. Unlike the other search
  engines' domain limits, Gigablast lets the
  searcher include paths to limit to a certain
  section of a site

  presentations of greatest interest to you

  Charter) ask Google to include not only exact
  matches but also what it thinks are synonyms for
  each of the keywords. In Its Search results,
  Google highlights synonyms in bold. Excluding the
  original word from the query will help to
  compiled a goodly list of synonyms

Word order matters

  matters

  keywords at once

33
Repetition Matters

• Repetition matters when it comes to keywords
  weighting you queries

• Pipe systems gas
• Pipe systems gas gas
• Pipe systems pipe pipe gas gas
• Multiple iterations of product names or nouns
  seem to favor shopping sites (especially true if
  the name is plural (e.g., scooters)
• Just because youre not getting different results
  for the second or third iteration doesnt mean
  you wont get different results for the fourth or
  fifth iteration

34
Search a Particular Date Range

• An undocumented but powerful feature of Googles
  search is the ability to search within a
  particular date range
• A date range search has nothing to do with the
  creation date of the content and everything to do
  with the indexing date of the content
• Google can index pages several times and each
  time it does so the date on it changes.
• Google doesnt stand behind the results of a
  search done using the date range syntaxes.

35
Search a Particular Date Range

• Why
• It narrows down your search results to fresher
  content
• It help you dodge current events
• It allows you to compare results over a period of
  time

36
Search a Particular Date Range

• How
• Daterangestartdate-enddate
• Date must be expressed as a Julian date
• Dont mix this syntax with
• Link
• Magic words (stocks , phonebook)

37
Search a Particular Date Range

• Julian date
• A Julian date is just one number.
• It is the number of days that have passed
• since January 1,4713 B.C. (Julian dates
• begin at noon)
• Convert Julian dates online

• than last name and state
• Phonebook
• Search the entire Google phonebook

39
What can we do with googlespelling

• There is no law stating that
• every page must be spellchecked
• before it goes online.
• Use this to your advantage as
• a researcher and it is worth
• taking a look at results despite
• misspellings.
