Count Specific Word by Row in DAX - powerbi

Question

I'm trying to count the number of times the word "text" appears per row in Power BI. I've done a lot of google searching and seen examples like this:
Formula :=
CALCULATE (
COUNTROWS ( FILTER ( 'TestData', FIND ( "text", 'TestData'[Description],, 0 ) > 0 ) ),1=1
)
but it isn't quite getting me there. How can I get for row 1, a result of 1 and row 2, a result of 3.
CREATE TABLE [dbo].[TestData](
[ID] [int] IDENTITY(1,1) NOT NULL,
[Description] [varchar](100) NULL
) ON [PRIMARY]
GO
SET IDENTITY_INSERT [dbo].[TestData] ON
GO
INSERT [dbo].[TestData] ([ID], [Description]) VALUES (1, N'this is my demo text')
GO
INSERT [dbo].[TestData] ([ID], [Description]) VALUES (2, N'text text demo text')
GO
SET IDENTITY_INSERT [dbo].[TestData] OFF
GO
Expected Result
ID Description Text Word Count
1 this is my demo text 1
2 text text demo text 3

Answer 1

Calculated Column:
=
VAR MySearchText = "text"
RETURN
DIVIDE(
LEN( Table1[Description] )
- LEN( SUBSTITUTE( Table1[Description], MySearchText, "" ) ),
LEN( MySearchText )
)
Measure:
=
VAR MySearchText = "text"
VAR ThisDescription =
MIN( Table1[Description] )
RETURN
DIVIDE(
LEN( ThisDescription )
- LEN( SUBSTITUTE( ThisDescription, MySearchText, "" ) ),
LEN( MySearchText )
)
though note that both of these will return positive counts where MySearchText is found within other words: a description of "this is textual", for example, will return 1.

I don't believe DAX has a textsplit function, but you can do something like this to ensure you don't pick up words of which text is a substring.
Text Count (DAX) =
VAR pad = SUBSTITUTE(" " & [Description] & " ","text","~text~")
VAR lenPad = LEN(pad)
VAR lenText = LEN("~text~")
VAR lenRemText = LEN(SUBSTITUTE(pad,"~text~",""))
RETURN (lenPad-lenRemText)/lenText
```
