When i am querying sharepoint via sharepoint search api , it is not doing partial search of a word.
For example, if i have a keyword called "backup" in my content and if i search for the same as keyword, sharepoint api is able to fetch the results for that keyword. But if i do partial search of the keyword as "back" , it is not giving any result.
All my rest api results are containing the word "Microsoft.Office.Server.Search.REST.RelevantResults", what it means?. I just want to know what kind of search algorithm or methodology which is used by Sharepoint Search API?
