Search PDF, PPT and DOC files with Google

If you want to search any specific presentation slides in PDF, PPT or PPTX format, you can use some Google hacks!.

You can specify filtering option in Google so that search results will contain only areas or sections you are interested in.

For example, if you would like to search presentations on "C++ programming" then you can tell Google  to show only results with presentation slides by specifying filetype option

C++ programming filetype:PDF

similary for ppts,

C++ programming filetype:PPT

C++ programming filetype:PPTX

or If you need to search only documents related to C++ programming,

C++ programming filetype:DOC

C++ programming filetype:DOCX
