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?

Hi, All Friends,
Whatever. Can we try to build a regex for 'The City of London
London Great London UK ' ?
It could be something like '[\w\s]+[\s-]+[a-z]+[\s-][\s\w]+'.
[\s-]+[a-z]+[\s-] is catered for some people think that 'City of
London' is 'City-of-London' or 'City-of-London'.

Do you really want "The City of", by itself, to be one of the detected
phrases? eg 'The City of London London Great London UK The City of
Liverpool'.
