Same name and namespace in other branches

Form submission handler for biblio_search_form().

When we submit a search, we revoke all current filters since search and filtering are considered two different concepts things conceptually.

But we store the results as a filter (which is just a list of node ids that matched the search request) so that we can reorder or export the search results like with any other filter. The filter has three components: ('search', <list of node ids>, <search keywords>). The second component (the filter value) is empty when submitting keywords. In biblio_db_search, we fill the second component with the list of nids matching our keywords, as returned by node_search. We store the keywords only for showing them in "Search results for <keywords>".
