Abstract
Esta solicitud se refiere a la indexacion de un vector de entrada contenido en un conjunto de vectores de una pluralidad de conjuntos de vectores. La indexacion comprende la realizacion, en el caso de que el vector de entrada esté contenido en un conjunto de vectores de un grupo predefinido de uno o más conjuntos de vectores de la pluralidad de conjuntos de vectores, de un procesado específico que está adaptado a una característica de los conjuntos de vectores en el grupo predefinido de conjuntos de vectores y que solamente es aplicable en el caso de vectores de entrada contenidos en conjuntos de vectores con la característica. La indexacion comprende de manera adicional la realizacion, en el caso de que el vector de entrada no esté contenido en un conjunto de vectores del grupo predefinido de conjuntos de vectores, de un procesado general. La solicitud se refiere además a una determinacion de acuerdo de un vector objetivo contenido en un conjunto de vectores de una pluralidad de conjuntos de vectores en base a un índice asociado con el mencionado vector objetivo.
