Search Method
Actual processing of the search begins here. DataSet to store the search results is created here and ProcessDirectory method is called.
'********************************************

' Search Method
'
' Search the entire site
'
'********************************************
Public Function Search(ByVal targetDirectory As String) As DataSet
'If the site is in English then use the server HTML encode method
If Searchs.Site.EnglishLanguage = True Then
'Replace any HTML tags with the HTML codes
'for the same characters (stops people entering HTML tags)
m_searchWords = m_page.Server.HtmlEncode(m_searchWords)
'If the site is not english just change the script tags

End If
If m_dstPages Is Nothing Then
m_dstPages = Searchs.PagesDataset.Create()
End If
ProcessDirectory(targetDirectory)
Return m_dstPages
End Function
ProcessDirectory Method
The ProcessDirectory loops through all the files and calls the ProcessFile method. Later, it also loops through the subdirectories and calls itself.
'*********************************************
'
' ProcessDirectory Method
'
' Files in the directories are searched
'
'********************************************
Private Sub ProcessDirectory(ByVal targetDirectory As String)
Dim fileEntries As String()
Dim subdirectoryEntries As String()
Dim filePath As String
Dim subdirectory As String
fileEntries = Directory.GetFiles(targetDirectory)
' Process the list of files found in the directory
For Each filePath In fileEntries
m_totalFilesSearched += 1
ProcessFile(filePath)
Next filePath
subdirectoryEntries = Directory.GetDirectories(targetDirectory)
' Recurse into subdirectories of this directory
For Each subdirectory In subdirectoryEntries
'Check to make sure the folder about to be searched
'is not a barred folder if it is then don't search

Path.GetFileName(subdirectory), vbTextCompare) > 0 Then
'Call the search sub prcedure to search the web site
ProcessDirectory(subdirectory)
End If
Next subdirectory
End Sub 'ProcessDirectory
ProcessFile Method
The ProcessFile calls the GetInfo which returns the Searchs.Page object which contains all the information of the particular file. Later, it checks if the matchcount is greater than 0 and calls the CheckFileInfo to clean up the information stored in the Page object. It then stores the file in the PagesDataset.
'*******************************************************
'
' ProcessFile Method
'
' Real logic for processing found files would go here.

Searchs.PagesDataset.StoreFile(m_dstPages, srchFile)
End If
End If
End Sub 'ProcessFile
GetInfo Method
The GetInfo method's main task is to get the data of the file. It calls the shared method Searchs.FileContent.GetFileInfo where much of the work is done.
