Term normalization is the process of converting multiple terms into a single term for indexing and retrieval. By normalizing various terms into one, you increase the consistency of the search results. There are several common classes of term normalizations:
Spelling variants, such as customisecustomize
Compound terms, such as data basedatabase
Spelling corrections, such as febuaryfebruary
Aliases or name variations, such as MS WordMicrosoft Word
The ATG Search core dictionary contains large numbers of general term normalizations, and administrators can create their own using custom terminology (see the Custom Terminology section).
