    Hi adeelnazir786 ,

     

    We can create a measure and use it in visual filter to meet your requirement:

     

    VisualControl = 
VAR Title =
    SELECTEDVALUE ( 'data'[title], BLANK () )
RETURN
    IF (
        IF (
            ISFILTERED ( 'Sheet1'[key] ),
            CALCULATE (
                COUNTROWS ( 'Sheet1' ),
                FILTER ( 'Sheet1', CONTAINSSTRING ( Title, [key] ) )
            ) > 0,
            TRUE ()
        )
            && IF (
                ISFILTERED ( 'Sheet2'[key] ),
                CALCULATE (
                    COUNTROWS ( 'Sheet2' ),
                    FILTER ( 'Sheet2', CONTAINSSTRING ( Title, [key] ) )
                ) > 0,
                TRUE ()
            )
            && IF (
                ISFILTERED ( 'Sheet3'[key] ),
                CALCULATE (
                    COUNTROWS ( 'Sheet3' ),
                    FILTER ( 'Sheet3', CONTAINSSTRING ( Title, [key] ) )
                ) > 0,
                TRUE ()
            ),
        1,
        -1
    )

v-lid-msft ,

 

I've been use part of your formula which returns the number of findings, that really working 😛 

CALCULATE (
                COUNTROWS ( Sheet1 ),
                FILTER ( Sheet1, CONTAINSSTRING ( Title, [key] ) )
            )

 Thanks & Regards,

Adeel
