Creating sql string for vba query with wildcard characters

Excel 2010 vba

I'm taking a text string from a cell
Splitting that into an array.

The code works fine UNLESS i only have one Token.  i.e.   FLAPPER  OR  VALVE

I'm creating the end of the "WHERE" clause in my sql statement.

for ONE word,   two word and/or  three word strings.

    lk = "Like"
    lm = " WwgCore.RICHTEXT "
    
    cD = Trim(cD)
    cD = Replace(cD, "  ", " ")
    cD = Replace(cD, ",", " ")
    cD = Replace(cD, "#", "")
    cD = Replace(cD, """", "")

    ' how many items are in the cell ?  build an array
            
    nF1 = cD
            
    cArrSql = Split(nF1, " ")
            
    ' search through the cell requests tokens.
    For x = LBound(cArrSql) To UBound(cArrSql)
        If x = UBound(cArrSql) Then
            nF1 = Trim(nF1 & " " & Chr(34) & "%" & cArrSql(x) & "%" & Chr(34))
               
        Else
            If x = 0 Then
                nF1 = Trim(Chr(34) & "%" & cArrSql(x) & "%" & Chr(34) & " AND" & lm & lk & " ")
            
            Else
                nF1 = Trim(nF1 & " " & Chr(34) & "%" & cArrSql(x) & "%" & Chr(34) & " AND" & lm & lk & " ")
            
            End If
        End If
    Next

    rng2 = nf1

The end of my WHERE clause is:
strsql = strsql & "WHERE WwgCore.RICHTEXT LIKE " & rng2 & ";"

for 2 tokens the string looks like this :
rng2 =   "%FLAPPER%" AND WwgCore.RICHTEXT Like "%VALVE%"  and the code works fine

ultimately nf1 for One Word token should be passed as  "%FLAPPER%"

per above example:

But does not work for ONE word tokens
