NGRAM_OLD

Syntax

NGRAM_OLD(<string>; <string regular expression for separator>; <number for length>; <number for length>; <number for length>;....)

Description

Returns sub sequences of N words of a given text. To see subsequences of N characters of a given text, refer to NGRAM. Datameer tries to match entire record without automatically adding ^ or $ to the regular expression. But if the record has multiple lines, then this must be accounted for with (?s) or line terminators.
