I just copy the noise words file from \Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\FTData
into my app, and use it to strip noise words.
Public Function StripNoiseWords(ByVal s As String) As String
Dim NoiseWords As String = ReadFile("/Standard/Core/Config/noiseENU.txt").Trim
Dim NoiseWordsRegex As String = Regex.Replace(NoiseWords, "\s+", "|") ' about|after|all|also etc.
NoiseWordsRegex = String.Format("\s?\b(?:{0})\b\s?", NoiseWordsRegex)
Dim Result As String = Regex.Replace(s, NoiseWordsRegex, " ", RegexOptions.IgnoreCase) ' replace each noise word with a space
Result = Regex.Replace(Result, "\s+", " ") ' eliminate any multiple spaces
Return Result
End Function
