This forum's view

I tried to do the same search that you described:

www.keil.com/.../search.asp

As you say, the second hit is "Winbond memory(SPI interface)" - which is about an 8051-derivative
http://www.keil.com/forum/docs/thread10906.asp

However, note that the originator of that post specified the architecture as 'Non-Specific (Generic)'

Presumably, as the search engine cannot tell that it is not related to your chosen architecture, it has to assume that it might be relevant - and so includes it in the results.

So another search option is required: to include or exclude "generic" posts.

And that is the fundamental flaw with this filtering idea - it relies on people correctly classifying their posts!

Often, a thread starts on an architecture-specific question, but later moves on to - or includes - non-specific issues...

And you have your answer :)

Don't change the family in a answer.. use that from original post.

And I think it's better than most of reader/writers here, which are able to use the family section are reading what they want
than given rookies a flat platform to spam..

And I mean that I CAN use.. not MUST use a filter.
