Search Tip of the Month (November 2011)

Search for PPTs

Many people are interested in finding PowerPoint presentations (PPTs) of others. Especially, when they are preparing a presentation, it would help them to learn how others have made nice PPTs, some useful techniques & tips, and finding some attracting templates, etc. (Of course, I do this!!!)

>So, if you want to search only PowerPoint files, you can still limit your search only for PPT files with Google. Follow these steps:

1. Go to 'Google Advanced Search', and type your search query in the search box.

2. Then select the 'File type' as 'Microsoft Powerpoint (.ppt).

3. Then click on 'Advanced Search'.

Oh, it works!!!

>There is also a shortcut for that. (hope you prefer shortcuts :)

In simple search box of Google, just type as follows:

"searching techniques" filetype:ppt

(You may note here, the file type is 'ppt')

Yes, it also works :)

Synonym Search

If you want to search not only for your search term but also for its synonyms, place the tilde sign (~) immediately in front of your search term.

Example: ~fast foods

This will also retrieve terms such as junk foods, quick foods, etc.

BUBL

BUBL is an Internet-based information service developed for the UK higher education community. BUBL stood for BUlletin Board for Libraries. However it is now known as the BUBL Information Service. It can be described as a directory or a gateway for online resources. BUBL staff evaluates new resources and services on the Internet, and decide whether or not they are suitable for inclusion on the service. Then these resources are categorized according to their subject content and arranged under the relevant subject category along with the URL. This arrangement is known as the BUBL Subject Tree which is based on the Dewey Decimal Classification. You can either browse the categories or search the database for locating resources. Since the resources listed here are selected, evaluated and very often annotated, users can find some quality information using the service.

Boolean Operators

In searching, Boolean operators are used to combine two or more search terms in order to show their relationship to the database. Basically, there are three (03) Boolean operators and they are explained as follows:

• AND - combines search terms so that each search result contains all of the terms. For example, education and technology finds articles that contain both terms. The famous search engine Google supports this technique. Actually, in Google, there is no need to type AND, because it connects two terms with AND combination by default.
• OR - combines search terms so that each search result contains at least one of the terms. For example, education or technology finds results that contain either term. In Google, you have to type the OR operator between two search terms, with a space in both sides, as shown in the above example.
• NOT - excludes terms so that each search result does not contain any of the terms that follow it. For example, education not technology finds results that contain the term education but not the term technology. In Google, you can use this technique by typing "space & minus sign" before the term that you want to exclude. Example: education -technology

Try these searching techniques with Google and let me have your feedback.
