Subject What can cause the exception bellow
Date Wed, 17 Aug 2016 20:45:34 GMT
Hi,

SELECT explode(context_ngrams(sentences(lower(text)),
array(null,null,null), 25))
AS x
from andy_tweets
where
regexp_extract(lower(text), '(^.*?)(\\bclinton\\b)(.*?$)', 2) = 'clinton'
and
regexp_extract(lower(text), '(^.*?)(\\bpetition\\b)(.*?$)', 2) = 'petition';

The statement above causes exception below. What can be a problem?
