Containsstringexact or containsstring but NOT substring, only whole selected word?

[SevsBo]

I'm having an issue where DAX for eiher Containsstring or Containsstringexact is returning partial matches. I know this is by design but I am wondering if there is a way to only match for specific word, not partial matches, or would I have to specifically omit the words I do not want captured?

As an example:

containstring (..., "Red Box") ||

containstring (..., "Green Box") 

I would only want to show words that are either "Red Box" or "Green Box", but not "Large Red Box" or "Gold Plated Green Box".

Would I have to do something like this for each one I want to omit or is there a better DAX expression to only get requested results?

containstring (..., "Red Box") && NOT (containstring (..., "Large Red Box"))  ||

containstring (..., "Green Box") && NOT (containstring (..., "Gold Plated Green Box"))

Hi, @SevsBo 

Since you didn't provide me with some test data, I assumed some data myself for testing:

You can then create a Calculated column to determine the original name if it is Red Box or Green Box, and null if it is not:

ExactMatch = 
IF (
    ([Product Name] = "Red Box") || ([Product Name] = "Green Box"),
    [Product Name],
    BLANK()
)

Then create a Measure:

ExactMatchMeasure = 
COUNTAX (
    FILTER (
        'Table',
        NOT(ISBLANK([ExactMatch]))
    ),
    [ExactMatch]
)

Finally drag the created Measure to the Filters panel to filter the data:

I have attached the pbix file for this simple example below, I hope it helps.

I hope my suggestions give you good ideas, if you have any more questions, please clarify in a follow-up reply.

@SevsBo , Try using

VAR RedBox = "Red Box"
VAR GreenBox = "Green Box"

RETURN
IF (
CONTAINSSTRING([YourColumn], RedBox) &&
(
LEFT([YourColumn], LEN(RedBox)) = RedBox &&
(LEN([YourColumn]) = LEN(RedBox) OR MID([YourColumn], LEN(RedBox) + 1, 1) = " ")
) ||
CONTAINSSTRING([YourColumn], GreenBox) &&
(
LEFT([YourColumn], LEN(GreenBox)) = GreenBox &&
(LEN([YourColumn]) = LEN(GreenBox) OR MID([YourColumn], LEN(GreenBox) + 1, 1) = " ")
),
TRUE,
FALSE
)
