Lemmatise full text search so that plural names are also found

In full text search we have the behaviour that if we have a folder with a plural name like: "bananas" and we try to search it by writing "bananas" in full text search the folder it isn't found.

If we search for "banana" instead the folder is found.
This related to elasticsearch and is a expected behaviour for now.

We should be able to do a full text search with plural or singular names.
