I guess I see what you mean. Teoma seems to be more condensed or concentrated (don't know how to say it than Google. I just tried to search for a typical M$ BSOD with the following info given
***ndis.sys-address F991971B base at F9919000,DATE STAMP 3d6de4c3
I used the following search query (pretty straight forward one) for both engines
ndis.sys + stop:0x000000d1
Google provides a bunch of results from forums where people reported similar problem. I could go and see if anybody posted a link to a M$ KB article, but most likely it would be something from MSDN. Teoma seems to be less affected by caching numerous online boards. The fifth link brought to a page with a list of M$ KB articles, and from where I was just one click from the target.
I'll bookmark Teoma, thanks, and will try to use again.
P.S. I could've achieved the same results by going directly to M$ KB and searching for
0x000000d1 AND Ndis.sys
0x000000d1 OR Ndis.sys
The first query wouldn't work, because the stop error ends with 1d, not with d1 as was reported I think the best search is the one you know how to use.
