Automatic inclusion of English/American spelling variations - new SET command increases convenience of searching STN
Have you ever wondered whether including spelling variations of certain terms (such as sulfur or sulphur and aluminum or aluminium) in your search query would improve the retrieval of your answer sets? Now you can be assured of maximum retrieval by employing the new SET SPELLINGS command.
With SET SPELLINGS ON, your search terms, including those with left and/or right truncation, will be automatically supplemented with spelling variants. In addition, when there is a common alternate term for your search term, that alternate term will be automatically added to your search strategy. Terms in this latter category typically are alternative words for the same object in English-speaking countries around the world.
When SET SPELLINGS is used, separate postings for each version of the search term are provided, as well as a combined total for the postings.
In databases with search term charges, no additional search term costs are incurred due to use of SET SPELLINGS.
