        This method should throw an UnsupportedOperationException if this operation is not supported by the backend user store.

        Specified by:
        findUsers in interface UserProvider
        Parameters:

      • findUsers

        public Collection<User> findUsers​(Set<String> fields,

                                          int startIndex,

        Searches for users based on a set of fields and a query string. The fields must be taken from the values returned by UserProvider.getSearchFields(). The query can include wildcards. For example, a search on the field "Name" with a query of "Ma*" might return user's with the name "Matt", "Martha" and "Madeline".

        The startIndex and numResults parameters are used to page through search results. For example, if the startIndex is 0 and numResults is 10, the first 10 search results will be returned. Note that numResults is a request for the number of results to return and that the actual number of results returned may be fewer.

        This method should throw an UnsupportedOperationException if this operation is not supported by the backend user store.
