SearchUnit Documentation: Indexing: ...programmatically

This Windows Forms example is intended to demonstrate a basic programmatic implementation. From the button click event, the website source is imported and the index fully built ready for searching.

Reference these DLL's in your project, KeyotiX.SearchEngine.Core, KeyotiX.SearchEngine.License, KeyotiX.Text.LemmaGenerator.dll, KeyotiX.Text.MSOffice.dll - where X is 2 for .NET 2 and 4 for .NET 4

'---Search Index

        Dim res As SearchResult = sa.Search("search terms", 1, 10) 'res now holds a collection of ResultItem objects

        End Sub
End Class

The try-finally constructs ensure that the index is closed even if an exception occurs.
