 ===== Notes =====
+This searches for a value associated with a given key. If an exact match is not found, the result will depend on how the input port "Value If Not Found" is defined. If a default value is defined by this port, that value will be returned. Otherwise, the execution will an error and the model execution will be interrupted.
+It is also possible to search for an approximate match using a [[Calculate Value]], [[Calculate Map]], [[Calculate Categorical Map]] or [[Calculate Lookup Table]]. See the "Lookup Table Operators" description on the [[http://csr.ufmg.br/dinamica/dokuwiki/doku.php?id=image_expression_type#operators|Image Expression Type]] documentation.
