..Stemming is used to enable the stemming and to define the language used to perform a stemming in a full-text index defined by programming.

The stemming is used to perform searches on a full-text index while taking the variations of a given word into account. This feature is not interesting for the knowledge databases and it allows you fo indifferently find words in singular or plural form.

Example

MyFullTextIndex is FullTextIndex Description
...
MyFullTextIndex..Stemming = nationEnglish

Syntax

<Name of Full-Text Index>..Stemming = <Language>

<Name of Full-Text Index>: Character string (with or without quotes)

Name of full-text index used. This name was defined by the FullTextIndex Description type.

Remarks

The management of synonyms (..Synonym) must not be enabled if the stemming is enabled.
The management of accented characters (..AccentuationSensitive) must be enabled if the stemming is enabled.
Because of grammatical exceptions (irregular verbs in English, verbs of third group in French, ...), some conjugations may not be grouped together (for example, a search for "fly" will not found the records containing "flown") or some plural forms may not be grouped with their singular form (foot/feet for example).
