Counting occurences in a BIG text field

[arth78]

Hello,

I'm a new user of PowerBI and I would like to count the occurences of a word in a single column (which is a big text field).

The difficulty is the field is a real mess... This is an exemple of a SINGLE LINE

"25/04/2014 YBE blablabla...

26/01/2009 MPR ras

25/01/2009 MPR blablabla...

18/02/03 STA1: blablabla..."

Yes, this is a single line, and I have thousand like this in my column.

My main goal (per example) is to know how many times appear the word "MPR" in the column, and as you can see, there's multiples occurences of "MPR" in a single line.

I have tried a lot of things but nothing fit to my specific need...

Any help would be appreciated.

I would calculate this in the Edit Queries window.  I would Add a Custom Column and use a formula like the following:

 = List.Count ( Text.Split ( [BIG text field] , "MPR"  ) ) - 1

It will split each BIG text field using MPR as a delimiter and then count how many substrings result. 

Subtract 1 because Text.Split will always return 1 substring if nothing is found, or 1 more substrings than the number of "hits" you are looking for.
