Hi, Peter,
How to define word boundary as either by using
^ , space, or $
So that the following can be done
fox fox is a repeat
foxfox is not a repeat but just one word.
Do you want repeated phrase (list of words) ore repeated words?
For repeated words (including unicode-chars) you can do:
(\b\p{L}+\b)(?:\s+\1)+
I'm not quite sure how to translate this to PG, but in JAVA it works.
