This thing is addressing problems that dont exist. Its solution-ism at its worst. We are dumbing down machines that are inherently superior. - Gilfoyle

What your experiance say ?

That you need more information before you start. Most important being:

Is it always slow, or it this unusual?

Is everything slow or just one query?

It's not a database error. The search results aren't kept around long (for space reasons I would assume). Trying to access a search link after the expiry produces that application error. It's not as if it's saying 'cannot connect to SQL'
