I am very interested in feedback on this as well.  I am currently working on
an EAD search tool in Perl using CGI.  What features do users want?  My
approach was to allow the user to pick from some preset 'fields'
(Scope/Content, Geogname, Persname, Date, Abstract, Full-Text, etc.) which
corresponded to various elements or sets of elements.  Is this granularity
useful or would a keyword search do just as well?  I also added the ability
to specify individual years or ranges of years to limit the search (using
the collection-level <unitdate/>)--this slows the program down a bit, and
was a pain to write; is it worth having?

One things I haven't implemented is relevance sorting.  Is that necessary?
If so, what factors would influence each matching finding aid's relevance

My search results display each EAD document's title, unitid, origination,
extent, and abstract.  No effort is made to necessarily display the portion
of the document where the search terms were found (as, say, Google does).
Is this a bad thing?  My thoughts are that the abstract is more revealing
than a mid-finding-aid excerpt, but I'm not entirely certain about this.

(On a semi-related note, if anyone has experience with the Perl XML::XPath
module, please e-mail me.)
