About field selectors

The simplest way to filter big amounts of data are field selectors!
By this manner the function call is manipulated by an additional parameter ‘fieldselect’ that selects one or several fields of the returned value list.

fieldselect=(Fields) Provides only TOP 1 fields from ‘Fields’
fieldselect=(Fields:(LANG)) Provides TOP 1 fields and additional the field ‘LANG’
fieldselect=(Fields:(LANG,DOMAIN)) Provides TOP 1 fields, additional the fields ‘LANG’ and ‘DOMAIN’
