Implement a new query type that matches documents containing a specified field, regardless of the field's value. This is useful for filtering documents based on whether they have a particular field indexed. - Add FieldExistsQuery type in search/query/field_exists.go - Add FieldExistsSearcher in search/searcher/search_field_exists.go - Register query type in ParseQuery for JSON deserialization - Export NewFieldExistsQuery constructor
