%20 in filename ok?

how do search engines treat it?

[bonanza]

I've heard that search engines (particularly google) treat underscores as a word character and a hypen as whitespace as far as keywords are concerned, for example, the filename:

blue_red.html will match "blue_red" as a keyword and
blue-red.html will match "blue" and "red" as two separate keywords.

How about blue%20red.html? Anybody seen any behavior around this method one way or the other?

thanks.

I don't think G read "bla_bla" as "bla bla".
It does read "bla-bla" as "bla bla" though.

I work around it by using the filename as title and replace the underscore with space in the title.

I avoid spaces in the filename because for visitors
guneapig%20determination%20table%20design%20considerations isn't easy to read.. But I don't think they are a problem for searchengines.

I don't like the cosmetic/readability aspects of hyphens either, reminds me of e-le-men-ta-ry school books :-)
