Knowledge & Research Consultant Tip: Advanced search techniques in News with commands and LexisNexis SmartIndexing Technology™ scores
In instances when it’s difficult to determine the specific terms necessary to get the most relevant news articles due to general terms involved, combining appropriate special commands with LexisNexis SmartIndexing Technology relevancy scores and searching within the headline and lead of an article can help you achieve more relevant and manageable results.
Allcaps allows for looking for an acronym that also spells a common word or name, e.g., allcaps(RICO)
allows for looking for a proper noun (one letter or more capitalized). Example: caps(Apple)
Nocaps allows for looking for a word and avoiding its use as a proper noun or acronym. Example: nocaps(apple)
Combine with search terms. Example: allcaps(RICO) and money /5 launder!
Combine one of these with the Atleast command. Example: Atleast5(caps(Apple Computer))
Keep in mind, you can increase the minimum number of occurrences once you’ve run the search by utilizing the Atleast command in Search Within.
Combine with the Hlead segment. Example: Hlead(allcaps(RICO) and atleast5(allcaps(RICO))
Add the use of a LexisNexis SmartIndexing Technology score. Search example:
Hlead(Caps(Apple)) and atleast10(Caps(Apple)) and term(new products #85plus#)
Or use Search within and enter just the LexisNexis SmartIndexing Technology piece: term(new products #85plus)
Remember to review a relevant article for Subject or Industry terms to use the correct word(s).You can use a number greater than 85 for greater relevance.
Finally, use the LENGTH segment to indicate the minimum word length of articles.
Example: Length > 1200
Hlead(Caps(Apple)) and atleast10(Caps(Apple)) and term(new products #90plus#) and length > 2000
Best practice: Run your search with fewer restrictions to get feedback on what’s generally available. Add the above restrictions via Search Within. You can always remove the additional restrictions without having to do a new search—as in this screenshot.
