主题：分页加载如何模糊查询所有数据

设计一个分页加载窗户口，窗口加一个“TextBox”控件，怎样写代码才能实现模糊查询所有后台数据？主要是数据太多了，全部加载卡的要死。现在的代码只能查询当前页：

Dim txt As String = e.Sender.Text
Dim t As Table = Tables("物资字典")
If txt = ""
    t.Filter = ""
Else
    txt = "'*" & txt & "*'"
    t.Filter = "[物资编码] Like " & txt & " Or [上级编号] Like " & txt & " Or [物资名称] Like " & txt & " Or [规格型号] Like " & txt & " Or [计量单位] Like " & txt
End If

输入查询关键字卡的很，一个字一个字的往外蹦
