New SORT Option
Command Language users can now take advantage of a
new SORT command option to improve relevancy in retrieval.
The command format is: SORT <set> / <range
of records> / HITS. This SORT command
option creates a new set where records containing
the most occurrences of your search terms are placed
first in the set. This can save you both time and
money in reviewing results.
The new SORT command option is especially
useful in fulltext databases, such as Dialog NewsRoom,
when your search retrieves a large set. This new
feature is best used in combination with other fulltext
search techniques: restricting terms to the title
(/ti), descriptor (/de) and lead paragraph (/lp),
and preferring proximity operators to Boolean AND
and OR.
In the following
example, we are looking for stories that
report on the relationship of diabetes to
Alzheimer's disease. After opening
the current NewsRoom database (BEGIN 990),
the "same paragraph" proximity operator (S)
is used with the terms "diabetes" and "alzheimer?". The
command SORT S1/ALL/HITS then orders the
records by the number of times "diabetes" and "alzheimer" (and
variations) appear in a record.

Set Items Description
--- ----- ----------- |
 To help illustrate how the new SORT
feature works, change the KWIC setting to display
search terms with a minimum of surrounding text: |
?SET KWIC 2
KWIC is set to 2. |
 Enter the search terms: |
?S DIABETES (S) ALZHEIMER?
59409 DIABETES
24108 ALZHEIMER?
S1 1257 DIABETES (S) ALZHEIMER? |
 Display just
where the search terms appear in the record.
There are 4 "hits" in the first
two records
of the set: |
?TYPE S1/KWIC/1-2

 SORT the set so that the records are arranged
in descending order according to number
of occurrences of the search terms in each
record: |
?SORT S1/ALL/HITS
S2 1257 Sort S1/ALL/HITS |
 Display just where the search terms
appear in the first two records. The first
record in the set is now the one with most
number of hits: 37. It is followed by the
record with the next-highest number of
hits: 18. And so on through the entire set in
descending order by number of hits: |
?TYPE S2/KWIC/1-2
