Summary:	provide user feedback for missing (or invalid) search parameter

Description Juergen Ragaller 2008-02-23 08:02:55 UTC

currently the search usecase results in a error when the search string

a) is empty (occurs
when clicking on "Go" or when clicking on a language icon on the search results page (see
43816)
b) starts with a "+"
c) starts with a "*"

(maybe some more...)

I think it would
be nice to let the user know what happened and describe the problem on the (empty) search
results page

a) "Your search  must not contain more than 1 character"
b)/c) "Your search
 must not start with the keyword + or *"

I was trying to find the right place to check
the parameters and provide feedback

- regex matcher in lucene/sitemap.xmap?
- implement
the parameter checking in search.jx?
- or rather using java?

IMO the SearchGenerator should handle this, so it's a Cocoon bug. They would certainly be glad about a patch, though. Maybe we can ask on the Cocoon user mailing list if someone has already resolved this issue.

BTW, empty search strings are handled now (no search is issued).
