Content based search on PDF documents in SharePoint 2010

Hi,

We want to implement Content based search on the PDF documents uploaded to our SharePoint 2010 site. Currently, with regards to PDF, we currently have only metadata search and now client wants content based search.

The users scan hard copies of documents and save them as .pdf files. These pdf files they upload to SharePoint site.

I want to know if we deploy PDF iFilters to our farm and run a FULL crawl, will we be able to perform content based search on these PDFs? Will this be all?
