Search for a Document

From time to time, you may find the need to search for a document stored in the current or alternate database. A document search is often used when you need data from one document to populate fields in another document. This section describes several methods to search for a document in a Notes database.

How It Works

A wide variety of solutions can be used to locate a document in a database. This section illustrates how to use While loops, the GeTDocumentByKey method, and the Search method to retrieve a particular document.

ImplementationExample 1

In this first example, the GeTDocumentByKey method is used to search a particular view for a text string. If the text string key is found, a handle to the document is assigned to the Doc object. After they are assigned, objects on the document can be referenced or updated. In order to use this approach, the search key must reside in the first column, which must be sorted in either ascending or descending order.

To implement this solution, create a view where the first column in the view contains the search key. Sort the first column in either ascending or descending order. To locate the document, add the following code in a button, agent, or event. Be sure to replace KEY and VIEW with valid values in the following code example.

Dim s As NotesSession
Dim db As NotesDatabase
Dim view As NotesView
Dim doc As NotesDocument
Dim key as String
Set s = New NotesSession
Set db = s.CurrentDatabase

key = "John Doe"
Set view = db.GetView("VIEW")
Set doc = view.GetDocumentByKey(key, True)

Note

The GetdocumentByKey method includes a match parameter. Set the parameter to trUE to enforce a perfect match or FALSE to allow for a partial string match.

 

ImplementationExample 2

In this second example, the Search method and a static key are used to locate a document in the database. This approach can be a bit tricky because it requires delimiters, such as the vertical bars or double quotes, to separate the various parameters. This approach also requires a search string key, a DateTime value, a form name, and a field name. If multiple documents are returned, use the GetFirstDocument method to retrieve the first document or the Forall statement to loop through each document.

To implement this solution, add the following code in a button, agent, or event. Be sure to replace KEY, FORM, and FIELD with valid values in the following code example.

Dim w As New NotesUIWorkspace
Dim s As New NotesSession
Dim db As NotesDatabase
Dim doc As NotesDocument
Dim collection as NotesDocumentCollection
Dim key As String
Dim searchformula As String
Dim searchdate As NotesDateTime
Set db = s.CurrentDatabase
Set searchdate = New NotesDateTime("")

'-----------------------------------------------------------------
' Set the search key and search formula values
'-----------------------------------------------------------------
key = "VALUE"
searchformula = "Form=""FORM"" & FIELD="""+Key+""""

Set collection = db.Search(searchformula, searchdate, 0)
Set doc = collection.GetFirstDocument

 

ImplementationExample 3

In this third example, the Search method and a dynamic key are used to locate a document in the database. As with the previous example, you will need to pay particular attention to enclose parameters in the correct number of delimiters (or quotes). Here, the actual search is a dynamic value and references a text string field on the current form.

Dim w As NotesUIWorkspace
Dim s As NotesSession
Dim db As NotesDatabase
Dim uidoc As NotesUIDocument
Dim collection As NotesDocumentCollection
Dim docA As NotesDocument
Dim docB As NotesDocument
Dim searchformula As String
Dim searchdate As NotesDateTime

Set w = New NotesUIWorkspace
Set s = New NotesSession
Set db = s.CurrentDatabase
Set searchdate = New NotesDateTime("")
Set uidoc = w.CurrentDocument
Set docA = uidoc.Document

searchformula = "Form=""FORM"" & FIELD="""+DocA.FIELD(0)+""""
Set collection = db.Search(searchformula, searchdate, 0)
Set docB = collection.GetFirstDocument

 

ImplementationExample 4

Finally, this last example illustrates how to loop through all documents in a particular view. If a field on each document matches a target value, then an action is taken. For example, using this approach, you could change all documents where the OWNER field equals a person's name such as John Doe.

Dim w As NotesUIWorkspace
Dim s As NotesSession
Dim db As NotesDatabase
Dim doc As NotesDocument
Dim view As NotesView
Set w = new NotesUIWorkspace
Set s = new NotesSession
Set db = s.CurrentDatabase
Set view = db.GetView("VIEW")
Set doc = view.GetFirstDocument

While Not(doc Is Nothing)
 If doc.FIELD(0) = "VALUE" Then
 msgbox "Found a match."
 ' do something here.
 End If
 Set doc = view.GetNextDocument(doc)
Wend
