Hello,

I'm trying to use SQL Server 2008 Express to index large quantities of
documents, it seems to work very well.

My problem started when I tried to use the same word-breaker used by
SQL Server in order to highlight the search terms from C#. With SQL
Server 2005 I simply used the same word-breaker found in the Binn
folder, which implemented IWordBreaker, but with 2008 it seems to use
NaturalLanguage6.dll (and NlsData*.dll, NlsLexicons*.dll) but this one
doesn't implement any interface that I know. So... can someone please
help me? how can I word-break from C#?

Thanks,
Superware

All word breakers implement the IWordBreaker interface:
http://msdn.microsoft.com/en-us/library/ms691079(VS.85).aspx. I don't know
if there are any .NET wrappers available for these, they're COM components,
so you may have to create your own COM interop wrappers.

Are you sure about this? I know word-breakers supplied by/for SQL
Server 2005 implemented IWordBreaker. It seems NaturalLanguage6.dll
doesn't but rather implement ILexicon, ITextContext ITextChunk, ect...
any ideas?

I'm not familiar with the ILexicon, ... interfaces. I have written word
breakers for SQL Server 2008 using the documented IWordBreaker. I also have
heard that some folks have written .NET word breakers, though I haven't
written any in .NET myself. You should be able to create wrappers around
IWordBreaker without too much trouble, but I think the main issue would be
performance...
