How to create this simple string?

[Miguel Dias Moura]

Hello,

I am working on ASP.NET/VB. I have this string:
Dim keywords() As String =
Request.QueryString("search").Split(CChar(""))

Now I want to define a new string like this:
keywordsSQL = CONTAINS (*, 'keyword(1)') AND CONTAINS (*, 'keyword(2)')
AND ... CONTAINS (*, 'keyword(i)')

keyword(1) and keyword(i) are the first and last values in keywords().

How can I do this?

Thanks,
Miguel
