There is a short of a function in the standard Postgres to do the following:It is easy to count the number of occurrence of words, but it is rather difficult to count the number of occurrence of phrases.For instance:A cell of value: 'Hello World' means 1 occurrence a phrase.A cell of value: 'Hello World World Hello' means no occurrence of any repeated phrase.But, A cell of value: 'Hello World World Hello Hello World' means 2 occurrences of 'Hello World'.'The City of London, London' also has no occurrences of any repeated phrase.Anyone has got such a function to check out the number of occurrence of any repeated phrases?
