Question

I’m using VB.NET and Linq to SQL to do search query. I’m using the Contains method of Linq to look up the input keyword. It’s like this note.note_content.Contains(InputKeyWord).

The problem is that If I search for the “cord” then “according” will also come up. I want the result to be matched with keyword only.

How do I do to search for the whole keyword with Linq ?

Thank you.

I’m assuming that the inputKeyword can appear at the beginning, any place in between and at the end of the note, therefore you need to have 3 OR clauses for the 3 possible places where it can appear. So, your LINQ where clause may end up looking like this.

note.note_content.StartsWith(InputKeyword & " ") OR _
note.note_content.EndsWith(" " & InputKeyword) OR _
note.note_content.Contains(" " & InputKeyword & " ")

This is not a pretty solution, but It should work. If you are adept with regular expressions, that’s an option with LINQ as well.
