an ASP Site Search Facility with VBScript and the FileSystem Object
Peter A. Bromberg, Ph.D.
A lot of developers have sites that need some kind of search facility, but
they either don't have access to the MS Indexing Service (Index Server for you
NT4.0 folks) or for whatever reason, it may not be feasible to install it or
have it running.
Fear Not! It's really easy to produce a professional - looking "Homebrew"
search facility, and unless your site is extremely large, you may be pleasantly
surprised at how fast it can be. All we need to do is use the built- in Scripting.FileSystem
object and its methods to iterate through a specified folder and it's subfolders,
examining the content of each file for the requested search term, and then populate
a list of regular HTML <A HREF... links with the results.
This can all be implemented in a single ASP page, so let's get "under
the hood", so to speak and look at some code.
First, we need to tell if our search form has been "autoposted",
so we write:
if Request.form("SearchText") = "" Then
.write "<head></head><BODY ><Basefont face="tahoma"><TITLE>Search
</h2></center><BR><div align="center" id=status></div><BR><BR>"
.write "<FORM ACTION=Search.asp METHOD=POST>"
.write "<INPUT TYPE=TEXT NAME=SearchText>Search Term<BR>"
'.write "<INPUT TYPE=TEXT NAME=SC VALUE=.>SCOPE (. or /)<BR>"
' Disabled above line to keep scope in current folder
.write "<INPUT TYPE=SUBMIT VALUE=FIND></FORM>"
Note here that we check to see if the Request.Form collection holds a value
in the "SearchText" member from a form post, and if it does not ,
we Response.write out our search form to the user. The comment with 'NOINDEX
is used to tell the script to ignore certain pages that we don't want to come
up in a search, I'll get to that in a moment.
Assuming that our user has filled in a search term on the form and posted it,
we come to the code after the "else" in our "if- then - else"
Set the Script timeout to a high enough number to let the search finish
' Grab the search term from the form post and convert
all to upper case
strSearchText = UCase(Request.Form("SearchText") )
' Create the FSO and Folder objects
Set objfso = Server.CreateObject("Scripting.FileSystemObject")
' Create a "scope" term that can be used
to set the scope of the search root folder
sc = Request.form("SC")
' comment out next line to enable SEARCH SCOPE (e.g.
"."=curdir, "/"=full site , "../"=one directory
' Set the starting folder to the specified directory
Set objFolder = objFSO.GetFolder(Server.MapPath(sc))
sResult ="<head></head><BODY ><TITLE>Search Results</TITLE><h2><Center>Search
in Articles</h2></center><BR><div align="center" id=status></div><BR><BR>"
' Call the Search function
if numItems = "" then numItems = "0"
' Create a nice client-side DHTML status <div>
with search result info
Files Found. <BR> <A href=search.asp>Search Again</a>"";</script></body></html>"
' Now here's the Search function ...
on error resume next
' Iterate through each file in this folder ...
For Each objFile in objFolder.Files
' Get the file extension -- to upper case for comparison
(Actually there's a GetExtensionName builtin method, but let's keep it simple)
sext = Ucase(mid(objFile.Name, Len(objFile.Name)-3, 4))
' You decide here what file extensions you want to
be searched ...
'if sext = ".HTM" or sext = ".TXT" or sext = ".ASP"
if sext = ".ASP" then
' OK now we gotta actually read in the file contents
so we can look for search term...
Set objTextStream = objFSO.OpenTextFile(objFile.Path,1)
strFileContents = objTextStream.ReadAll
strFileContents = UCase(strFileContents)
' AHA! if i put in "NOINDEX" in my private
file, it doesn't come up in the list ...
if instr(1,strFileContents, "NOINDEX",1) = 0 then ' skip files with
' OK now we look for our search term..
If InStr(1, strFileContents, strSearchText, 1) then
' We found it - increment our numItems counter, and
create a hyperlink for the file ...
numItems = numItems +1
sResult = sResult & numItems & ".) <A HREF="""
& objFile.Name & """>" & objFile.Name &
' Close out TextStream object
' Did we get any errors?
if err.number <> 0 then
response.write err.description & "<BR>"
' Ok, let's check the next file in this folder ...
'Here we recurse - for each subfolder in this directory,
run the Search function again
For Each objSubFolder in objFolder.SubFolders
' And friends, that's all there is to it - Instant
File Search capability for your site!
I am sure you can come up with plenty of enhancements to this basic concept! Enjoy.
