The Stemming property is used to enable stemming and to define the language used for stemming in a full-text index defined programmatically.
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 of no interest for knowledge bases, and allows you to search indifferently for words in the singular or plural.

Observaciones
  • The management of synonyms (Synonym) must not be enabled if the stemming is enabled.
  • The management of accented characters (AccentSensitive) must be enabled if the stemming is enabled.
  • Because of grammatical exceptions (irregular verbs in English, verbs of third group in French, etc.), 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).
