title: Measure that counts entries that contain a specific string
body: <p>I am making a report in which I have to show the take-rates of different items. Each item exists of a three letter string, and all items are pooled in one and the same column as a large string, separated by spaces. </p>
  
  <p>I am now trying to create a measure such that searches for a specific item in this column and counts in how many entries the string was found. I now that this is possible by creating a calculated column to find the entries that contain that item and then sum this column, however, it would be nice if this is achieveable in a measure.</p>
  
  <p>For example, a column could contain</p>
  
  <p>7AX 4U6 4U7</p>
  
  <p>5AZ 6AT 4U6</p>
  
  <p>609 606 543</p>
  
  <p>I would then like to be able to count how much entries contain 4U6 by a measure...</p>
  
  <p>Thanks in advance for your help </p>
