New Commands Help Lexis/Nexis Users Perform More Precise Online Searching


The Lexis/Nexis services are now offering new commands that enable users to conduct more precise searching. The commands aid the user in specifying the plural or singular of a word in a search, duplicating unique capitalization or searching for words or phrases with no caps, and specifying the frequency of a search term within a document. The enhancements are a direct response to customer requests for help in devising more precise searches on the online services offered by Mead Data Central, Inc.

Examples of the new search terms are as follow:

CAPITALIZATION

ALLCAPS: allcaps (aids) will find AIDS but not aids.

CAPS: caps (supervga) will find SuperVga, SUPERVGA, Supervga, superVGA.

NOCAPS: nocaps (supervga will find only supervga.

SINGULAR/PLURAL

SINGULAR: singular (dog) will find dog and dog's but not dogs or dogs'.

PLURAL: plural (dog) will find dogs and dogs' but not dog or dog's.

COMBINED: singular (dog) AND NOT plural (dog) will find dog but not documents in which dogs appears.

FREQUENCY
