# (c) cavaliba.com - tests / dataview "query" vs the user's own query

"""
A dataview's "query" is loaded into the search box on an explicit ?dv= switch
only, and never beats a query the request itself carries. The tricky one:
cv-search-form has action="", so submitting it from ".../list/?dv=NAME" POSTs
back to that same URL with "dv" still in request.GET - the query the user just
typed must win there.

Also: a view with an empty query doesn't clear the current filter, and a query
with characters the search box itself would reject is ignored.
