I've got a searching algorithm I'm using to filter a CustomListView.
I can enter a few space-delimited search terms into the search text box; e.g., using "android iphone" would not only match "android iphone" but also "iphone android".
It even works for partial "words"; e.g., "andro ipho" would basically match the same way as above.
I would love to be able to use it for a B4XTable! Anybody know how to do that?
(Next step would make this a fuzzy search, where best matches are listed first and partial matches are included further down the list (or sorted by Levenshtein distance).)

B4X:
'Does string txt contain all words in list s?
Private Sub ContainsAll(txt As String, s As List) As Boolean
Private does As Boolean = True
For Each item As String In s
does = does And txt.tolowercase.Contains(item.ToLowerCase)
Next
Return does
End Sub
Private Sub txt_Search_TextChanged (Old As String, New As String)
clv_Exercises.Clear
clvExercisesSelections.SelectedItems.Clear
If New.Length = 0 Then
For Each item As String In AllExercises
clv_Exercises.AddTextItem(item,item)
Next
Else
Private terms As List = Regex.Split(" ",New.Trim)
Private xlist As List
xlist.Initialize
For Each item As String In AllExercises
If ContainsAll(item,terms) Then
clv_Exercises.AddTextItem(item,item)
End If
Next
End If
