Sharepoint 2007 - search

I have a sharepoint site.. in that i have uploaded some docs in the doc library... that includes .pptx file saved as web page i.e. '.mht' file... Those docs are not appearing in the search result.. I have checked the FileTypes in cental admin search settings.. In that .mht file type is included.. can anyone tell me what i have to do to make the开发者_如何学Gose docs to appear in tje search result...?

Have a look at this page. It has a proposed solution for mht files.
