Searching with Boolean Logic and Proximity Operators

# data[].attributes.subject
Searching with Boolean Logic and Proximity Operators

# data[].attributes.body
Boolean "AND" will narrow your search by retrieving only documents that contain every one of the keywords you enter

Boolean "OR" expands your search by returning documents in which either or both keywords appear

Boolean "NOT"/"AND NOT" limits your search by returning only your firsst keyword but not the second

Boolean Logic Redux- this is not always simple

Proximity operators  (NEAR, ADJ, SAME, etc) can serve a similar function in formulating search statements

# data[].attributes.body
Use the plus + and minus - in front of words to force their inclusion

Use double quotes

Put your most important keywords first in a string

Type in keywords or phrases in lower case

Combine phrases with keywords

Figure out what you want to do

If you want to browse, start out by using a subject directory like Yahoo and then enter search keywords into a metasearch engine

If you want to locate a specific piece of information, go to a major search engine such as Google or a specialized database

If you want to retrieve everything you can on a subjects, you should try the same search on several search engines

Check the source

Read the web address- only a few are top level domains

Determine page authorship

Check the vital information- a reputable page will usually provide you with the following: last date page updated, mail to link for questions and comments, name, address, telephone number, email address

Check the content- you have to check for bias and determine objectivity

There are two kinds - library gateways and portals.  Library gateways are collections of databases and informational sites that are arranged by subject and they have been gathered and reviews by a specialist.
Subject specific databases are devoted to a single subject created by professors, researchers, etc.
When to use a library gateway or subject specific database:

when looking for high quality information sites on web

When looking for information on a specific topic such as archives

They are created and maintained by human editors that review and select sites for inclusion in their directories.  The resources are usually annotated and the amount is usually smaller.  Subject directories come in different types: general, academic, commercial, portals, and vortals.  Most subject directories have partnered with search engines to query their databases and search the web for additional searches.
Pros:

type organized directories
