How to Extend Stemming (e.g. plurals) to Technical Terms not Recognised by the Standard Stemmer (Doc ID 431611.1)

Last updated on JANUARY 30, 2022

Applies to:

Oracle Text - Version to [Release 9.2 to 11.2]
Information in this document applies to any platform.


The standard stemmer used in Oracle Text will not generate the plural form for words the stemmer finds as unfamiliar, for example technical terms such as firewall, fileset, etc.  In order for queries to find both the singular and plural forms of these terms, regardless of what is entered, the dictionary used by the stemmer will need to be extended.
