Answer 1

OK, I have a solution but I'm not convinced it is the most elegant.
Thanks to the following resource for a text.split function in DAX https://www.excelnaccess.com/text-split-using-dax/.
Create a base table named Table as follows:
Create 2 calculated tables with the following code.
New Table1 =
VAR myvalues =
ADDCOLUMNS ( 'Table', "Paths", TRIM( SUBSTITUTE ( SUBSTITUTE( [text],".","") , " ", "|" ) ))
RETURN
SELECTCOLUMNS (
GENERATE (
myvalues,
ADDCOLUMNS (
GENERATESERIES ( 1, PATHLENGTH ( [Paths] ) ),
"#word", PATHITEM ( [Paths], [Value], TEXT )
)
),
"id", [id],
"word", [#word],
"text", [text]
)
New Table2 =
VAR myvalues =
ADDCOLUMNS ( 'Table', "Paths", TRIM( SUBSTITUTE ( SUBSTITUTE( [text],".","") , " ", "|" ) ))
RETURN
SELECTCOLUMNS (
GENERATE (
myvalues,
ADDCOLUMNS (
GENERATESERIES ( 1, PATHLENGTH ( [Paths] ) ),
"#word", PATHITEM ( [Paths], [Value], TEXT )
)
),
"id", [id],
"word", [#word],
"text", [text]
)
Drag New Table 1 [id] to a slicer
Drag New Table 2 [id] and [text] to a table.
Create a measure as follows and drag it into the table.
Matching Words = IF(ISFILTERED('New Table1'[id]), COUNTROWS('New Table2')+0, 0)
Create a relationship between word and word as follows:
That should be everything.
