I have a query where I search for a string in a field of a document that should be a book or a film. The word must be present in one of the properties of a nested object called 'translations' or in another nested objecte called translations of a nested object called myproperty. It should be published in a certain range of dates. Moreover, it must match the locale 'en'.
With fuzziness auto I have strange results. If I look for "leade" I get 3 results. All of them get the word "leader". However, if I look for "leader" I get 5 results because now I get the word "leaders" too.
How is it possible? Is Elastic looking only for the next letter after the string I search? Is there a way to tell him to show "leader", "leaders" or even "leadership" if I search for "leade"?
I'm kind of new to more complicated Elastic queries and maybe I misunderstood something. Thanks
