This document vagely describes the ftss client library. libftss is a C++ library that implements the client side of the ftss protocol. To use libftss you must include libftss.h and link with libftss.
I'll give a quick overview of the API. Go see libftss.h for more information. It is self documenting code.
There are three classes you will need:
Use this class to connect to ftss. You also use it to execute searches with the search function. The search function gives you a FTSearch object which is documented below.
Use this class to walk through the hit list (search result list).
Use this class to get information about a document in a hit list. The address field is the fullpath to the document.
