Word documents can be processed by Abiword into any msword document into html, latex, postscript, text formats with very simple commands; i guess it also exposes some api which can be integrated into document parsers/indexers.
Spreadsheets can be processed by utilizing
ExcelFormat library
http://www.codeproject.com/Articles/42504/ExcelFormat-Library or
BasicExcel library
http://www.codeproject.com/Articles/13852/BasicExcel-A-Class-to-Read-and-Write-to-MicrosoftOr even the GNU GNumeric project has some api to process spreadsheets which can be used to extract text and index.
Code to extract text from PDF
http://www.codeproject.com/Articles/7056/Code-to-extract-plain-text-from-a-PDF-fileOverall, I guess there are bits and pieces available over the internet and some dedicated efforts are needed to assemble those and develop into a finished product, namely document indexer.
Wish you success!

parsing library) can strip text from PDFs. Every now and then someone
posts to the podofo mailing list with questions related to extracting
text for the purposes of indexing it in FTS capable database. Podofo
has excellent developer support. The maintainer is quick to accept
patches, verify bugs, add features, etc... Disclaimer: I'm not a pdf
nor podofo expert. I can't help you accomplish what you want.
