Use wildcards (* and ?) for filtering your arrays.

#Include <Array.au3>

Local $aTest
Local $aArray[5] = ["abcde", "aabcd", "bcd", "aeiou", "asdf"]
Local $aPattern[6] = ["*e", "aa*", "?cd", "*e*", "*d", "*d?"]

_ArrayDisplay($aArray, "Original Array")

For $i = 0 To UBound($aPattern) - 1
    $aTest = _ArrayPatternMatch($aArray, $aPattern[$i])
    _ArrayDisplay($aTest, "Filter: " & $aPattern[$i])

Func _ArrayPatternMatch($aArray, $sPattern)
    ;funkey May 17, 2010
    If UBound($aArray, 0) <> 1 Then Return SetError(1, 0, "")   ;no 1D-array
    Local $n = UBound($aArray)
    Local $aRes[$n], $j = 0
    $sPattern = "^\Q" & $sPattern & "\E$"
    $sPattern = StringReplace($sPattern, "?", "\E.\Q")
    $sPattern = StringReplace($sPattern, "*", "\E.*\Q")
    For $i = 0 To $n - 1
        If StringRegExp($aArray[$i], $sPattern, 0) Then
            $aRes[$j] = $aArray[$i]
            $j += 1
    If $j = 0 Then Return SetError(2, 0, "")    ;no match
    ReDim $aRes[$j]
    Return $aRes

Programming today is a race between software engineers striving to
build bigger and better idiot-proof programs, and the Universe
trying to produce bigger and better idiots.
So far, the Universe is winning.
