Filter Property

The DASL statement used to restrict the search to a specified subset of data. This property is set by the Application object's AdvancedSearch method. Read-only String.

expression.Filter

*expression   * Required. An expression that returns a **Search**object.

Remarks

The Filter property is set by the Filter argument when the Search object is first created.

Example

The following Microsoft Visual Basic/Visual Basic for Applications (VBA) example creates a new Search object. The event subroutine fires after the search has finished and displays the **Tag**and Filter properties of the Search object in addition to the results of the search.

Sub SearchInboxFolder()
'Searches the Inbox folder
    Dim objSch As Outlook.Search
    Const strF As String = _
    "urn:schemas:mailheader:subject = 'Office Holiday Party'"
    Const strS As String = "Inbox"
    Const strTag As String = "SubjectSearch"
    Set objSch = _
        Application.AdvancedSearch(Scope:=strS, Filter:=strF, Tag:=strTag)
End Sub

Use an AdvancedSearchComplete event subroutine to ensure the integrity of the data stored in the Search object.

Private Sub Application_AdvancedSearchComplete(ByVal SearchObject As Search)
    Dim objRsts As Outlook.Results
    Dim Item as Outlook.MailItem
    MsgBox "The search " & SearchObject.Tag & "has finished. The filter used was " & _
        SearchObject.Filter & "."
    Set objRsts = SearchObject.Results
    'Print out number in results collection
    MsgBox objRsts.Count
    'Print out each member of results collection
    For Each Item In objRsts
        MsgBox Item
    Next

End Sub
Searching String Text fields

When searching Text fields, you can use either an apostrophe (') or double quotation marks ("") to delimit the values that are part of the filter. For example, all of the following lines function correctly when the field is of type String:

sFilter = "[CompanyName] = 'Microsoft'"

sFilter = "[CompanyName] = ""Microsoft"""

sFilter = "[CompanyName] = " & Chr(34) & "Microsoft" & Chr(34)
