Hello


I'm looking for examples of functional requirements/specifications for
search engines for a project that I'm working on. The aim is to provide web
developers with a reference as to how search should function, what fields
in a database should be queried, how to handle wildcards, stop words,
operators, etc.


If someone has examples of something like this that they've used in the
past, or of general specs that can be used as a starting point for our
project, that would be much appreciated.


Many thanks in advance!
Thomas
