Is there a way to return a "did you mean X" (spelling corrections,
similar temrs etc) or "narrow/broaden your search with Y" (drilldown,
expand...) in a search result in SRU? Such feedback mechanisms are
standard in information retrieval systems like Google and Amazon since
Two answer my question: no there isn't :-( you can put stuff in
extraResponseData but that's it. How about adding an extra response
parameter "suggestedSearchRetrieveRequest" (optional, repeatable) that
contains parameters for another searchRetrieveRequest and (optional) the
number of records?
A response saying "you have 0 results" is dull but saying "You have 0
results but how about searching for X in the field Y then you will have
100 results" is smart (or the other way round "you have a lot of
results, how about narrowing your search with X or Y") - so do you want
your search engine to be dull or smart?
