I recent was asked the following question in an UtterAccess forum and thought the solution could be useful to someone else down the line.

I have an access database with hyperlinks to many protected word documents (write protection only).
The target is : user enters a search string in access and selects specific protected document.

In the thread I developed 2 possible solutions: (1) Open the document and highlight the search term throughout the document, (2) Open the document and the start the Find dialog and allow the user the control of what they do from that point on.
 

Find and Highlight Occurrances of a Term

One option is to open the document and highlight the search term throughout the document and you can do this by using code like:

'---------------------------------------------------------------------------------------

' sFileName     : Fully qualified path and filename with extension of the word document
'                 to search through
' sSearchString : The search term to look for
'
' Usage:
' ~~~~~~
' OpenWordDocAndSearch "c:\demo\Test.docx", "The"

'---------------------------------------------------------------------------------------
Function OpenWordDocAndSearch(sFileName As String, sSearchString As String)
    On Error GoTo Error_Handler
    Dim oApp            As Object
    Dim oDoc            As Object
    Const wdYellow = 7

    On Error Resume Next
    Set oApp = GetObject(, "Word.Application")
    If Err.Number <> 0 Then    'Word isn't running so start it
        Set oApp = CreateObject("Word.Application")
    End If
    On Error GoTo 0

    Set oDoc = oApp.Documents.Open(sFileName)
    oApp.Visible = True
    oDoc.Content.Find.HitHighlight FindText:=sSearchString

Error_Handler_Exit:
    On Error Resume Next
    Set oDoc = Nothing
    Set oApp = Nothing
    Exit Function

Error_Handler:
    MsgBox "The following error has occurred." & vbCrLf & vbCrLf & _
           "Error Number: " & Err.Number & vbCrLf & _
           "Error Source: OpenWordDocAndSearch" & vbCrLf & _
           "Error Description: " & Err.Description, _
           vbCritical, "An Error has Occurred!"
    Resume Error_Handler_Exit
End Function

Use the Find Dialog

Another option is to open the document and then start the Edit/Find dialog and allow the user the control of what they do from that point on. To do so, we can use a function like:

'---------------------------------------------------------------------------------------
' Procedure : OpenWordDocAndSearch
' Author    : Daniel Pineault, CARDA Consultants Inc.
' Website   : http://www.cardaconsultants.com
' Purpose   : Open the document and the start the Find dialog and allow the user the
'             control of what they do from that point on

    On Error GoTo Error_Handler
    Dim oApp            As Object
    Dim oDoc            As Object
    Dim dlgFind         As Object
    Const wdDialogEditFind = 112

    On Error Resume Next
    Set oApp = GetObject(, "Word.Application")
    If Err.Number <> 0 Then    'Word isn't running so start it
        Set oApp = CreateObject("Word.Application")
    End If
    On Error GoTo 0

    Set oDoc = oApp.Documents.Open(sFileName)
    oApp.Visible = True
    Set dlgFind = oApp.Dialogs(wdDialogEditFind)
    With dlgFind
        .Find = sSearchString
        .Show
    End With
