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 X tries to match the 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.
