[Koha] RFC: authorities search autocomplete behaviour

Hi, a quick question, based on your experience: once the autocomplete feature in authorities search (cataloguing) retreived several results, the user is expected to click on one of them if it is what he/she was looking for. What should the behaviour be?: a) The clicked authority record should be left in the search field (current) so the user fills some other search fields and then clicks 'Search' button. b) The clicked authority record is shown below so the user can review it and choose it if applicable. c) The clicked authority record is directly chosen for linking and the pop up window closes. Thanks in advance. To+
