LOL, 55,000 documents? Are you being serious? 55,000 is child's play. Seriously, I have an individual site with 1 million+ documents in it and that site isn't even our main file repository. I'd imagine that when everything is moved in, we'll have 3 million live documents growing at a rate of 500,000 to 1 million per year.
Seriously guys, reading some of these comments, I really have to wonder about your IT departments. I have a lot of work to do on my Sharepoint environment to optimize performance more, but damn, it sounds like a Ferrari compared to your Yugos.
Yes, it can handle that number of documents, but that is really irrelevant if you can't find anything. As you stated elsewhere, if you can't find anything then that is the fault of your IT department. Well guess what, most of us have shitty IT departments.
Let's find some examples:
* Sorting by date is useless as damn near every result has a date of the last few days, regardless of when it was really last modified
* Relevancy ranking is "dumb," being determined damn near at random
* No stemming of search terms
* Searching for say "library" returns every document library in the system
* Inability for user to determine if he is seeing a particular result because of special permissions or not.
* Inability to easily use controlled vocabularies.
etc, etc.
Now, granted, a lot of that can be attributed to a lousy IT department, but at the same time I think it says a LOT about the software when SP does not work well for many people here. SharePoint really is a great tool, when you dedicate a lot of staff and time to configuring it to work juuuust right.
