| Choosing Keywords |
|
The search engine gives
you the ability to perform simple searches or to take full advantage of
its sophisticated search syntax.
By default the keywords field will accept a list of words separated by
spaces as in the example shown below:
|
congress
economy policy
|
|
This query
will show all stories that contain the words congress, economy and policy.
The spaces are assumed to be Boolean ands (see section on Boolean
Operators), meaning that all terms are required to be in all stories
retrieved. This is only a small part of the potential power the Save search
engine offers. Features such as Wildcard Characters
and Proximity Operators are also available.

|
Search Types |
|
Boolean operators such as and,
or, not and near can be used anywhere in any
type of search. In the list of search types offered, the logic of the
boolean connectors is used, but in some cases you do not need to enter
the actual connector(s).
All of the Words:
This type of search assumes that spaces between words are treated like
the logical and, meaning that all of the terms
entered are required to be in all of the items found. A search for Congress
economy policy would return all stories that contain all three of
these words exactly as they are spelled. See the section on Wild
Cards for information on including alternate spellings such as economies
or economic.
Any of the Words:
This type of search assumes that spaces between words are treated like
the logical or, meaning that results may contain
just one of the words or possibly all of the words from your query. The
search congress economy policy would return all stories containing
the word congress or the word economy or the word policy.
Keep in mind that this type of search can produce large search results.
Exact Phrase: This
mode assumes that the space between words requires that the words be adjacent
to each other and in the exact order in which you enter them. Use
this type of search if you are sure the exact phrase, such as electronic
banking, must occur in the stories you are looking for.
Advanced: This
option enables you to take full advantage of search syntax. Instead of
having spaces automatically interpreted as logical connectors, you enter
the precise operators you want. You may also combine different operators
in one search statement. For further explanations of the search syntax,
see the sections below on Boolean Operators,
Proximity Operators, Field Searching and Wildcard Characters.

|
From Newest to Oldest:
Will return the found stories in reverse chronological order. Stories
that were most recently published will appear at the top of your result
list.
From Oldest to Newest:
Will return the found stories in chronological order. Stories that were
most recently published will appear at the bottom of your result list.
By relevance: Will return the found stories in an order that best
matches the search terms you have requested. The more frequently these
terms appear in a story, the higher its rank in the result list will be.
|
Setting the number of items displayed per page: |
|
This allows you to
specify the number of abstracts returned in your result list. The top
stories matching your search terms and based on the sort order that you
have selected will be listed.
