Stemming on Text searchIssue Customers will sometime ask for the details on Stemming used in Text search, e.g. whether there is any property to turn this feature on. This article tries to give a brief details about the same.ResolutionUnfortunately, there is no such property to check if the stemming is turned on or not. The system uses the Zing search engine to manage search functionality. Zing matches derived words with stemming, which uses an algorithm called the Porter Stemming Algorithm. It is most effective for English text but supports stemming in these languages( French, German ). Refer the product docs mentioned in the Additional information section to know more about these. Stemming is provided by third-party software. Therefore, we cannot provide details on its function, or check how it gets enabled - but you can access the algorithm's website: https://tartarus.org/martin/PorterStemmer/If you wish to see how the stemming works, it is suggested to enable "Debug Text Search" from the application navigator.When a user runs a text search, then at the bottom of the search results page will show the debug information, including the stemmed words from the search terms.For example, if a customerhas only English language, and searching for the word "help" returns the following:08:51:24.179: <<<<< START Query Analysis >>>>>other (not gif, sql)08:51:24.179: Query Type : ANDother (not gif, sql)08:51:24.179: Raw terms : helpother (not gif, sql)08:51:24.180: TSWordFamilyTerm: helpful(1326580), helping(1421663), helps(816034), helped(1387146), help(12448)other (not gif, sql)08:51:24.180: IDF Boosting:other (not gif, sql)08:51:24.187: help[12448] : 3.648211other (not gif, sql)08:51:24.187: <<<<< END Query Analysis >>>>>Therefore, the stemming algorithm takes "help" and finds the words "helpful", "helping", "helps" and "helped" are stemmed forms of this word, and locates these stemmed words in my text index. Only indexed words are included.We can't update the stemming rules, as we are using the third-party tool. We only implement it and add support for languages by adding a new version of the software.If customers don't want a particular word to return in the stemming, then this is not possible by default - but they can set up a Stop Word for the undesired stemmed word, so it is not returned in any searches.However, this stop word is for the text index in question and is not specific for the stemmed words.
