How to insert a pdf into specific area in my page

Question

I generally insert a PDF in a full page using

\usepackage{pdfpages}
\includepdfmerge[fitpaper]{./test.pdf, 10}

The above inserts the page completely with the PDF page.

I want to insert the PDF only into a small box within my page.

How can I do it?

What I want is as below: (but I want the text in my PDF to be searchable also). I don't want to insert it like an image.
