Re: Search (was: Web team meeting minutes)

Dave,

I see the main problem is not in search engine, but in the site engine !
It's just not database driven. So, I withdraw my words :)
Does web team consider changing web site engine ? I suggest not to use
home-made engines, since we have no power to support it, we do database
development, and we don't want to depend on specific person. There are
big open-source projects with stable, mature community and we could
just add fts capability we need, for example, to Drupal.
