The current "Document Type" search in querybean is structured in a way that most
ecologists will not use frequently. This search should be changed to be an
"Advanced" search that allows construction of boolean searches on fields from
arbitrary document types and that can be nested in arbitrarily complex ways.
The user interface would therefore eliminate the "Document type" list, and each
term of the search expression would need a new UI widget that allows the user to
choose which fields to search (from the various doctypes present in the
catalog). This new "advanced" tab should only show up in the UI when an "Expert
mode" checkbox (in the toolbar) is checked, to try and simplify the UI as much
as possible (anyone savvy enough to construct a complex boolean search can also
figure out how to turn on the feature, and it will only confuse most users).
The advanced search capability should be last in the query tabs. Other search
tabs should be evaluated and possibly moved into this expert category. The
setting of the "Expert mode" checkbox should be persistent between sessions.
