SharePoint 2013 Thesaurus or Synonyms

The Thesaurus feature in SharePoint is associated with the SharePoint Search Service Application. In SharePoint Search if you want to include synonyms also in Search results for specific keywords, you need to import a thesaurus file into SharePoint.

In case you search for IE and you want the Search Results to include IE and Internet explorer, you need to have a thesaurus file uploaded with these entries into SharePoint

Thesaurus file is normally used to specify synonyms for a single word or multiple words that occur in queries. The query is expanded based on the entries in the thesaurus. You create and maintain the thesaurus file in a system external to SharePoint 2013 before you import it into SharePoint 2013 to make the synonyms available to the search system.
It should be a .csv file with the columns Key, Synonym and Language

- In the Key column, enter the term (single or multiple words) that you want to trigger a synonym for when the term occurs in a query.

- In the Synonym column, enter the synonym (single or multiple words) that you want to add to the query if the term specified in the Key column occurs in a query. Synonyms consisting of multiple words will be added as phrases to the query.

- In the optional Language column, enter the abbreviation for the language for which the synonym should apply.If you leave this column empty, the query is expanded with the synonym regardless of the query language.
Note : Make sure there are no leading or trailing spaces around the terms

Example of a thesaurus looks like this :

IE,Internet Explorer
Internet Explorer,IE
UN,United Nations,en
