Search field is missing

[gjost]

The search page loads and the search button appears, but the search text field is missing.

Looks like it's only a problem if you click on the big "SEARCH" button on the home page.

• Works with the navbar search form
• topic and facility searches work
• creator and person fulltext searches work

Problem was the ui.views.searching.search_ui view code, which didn't assign a value to context['search_field'] unless there was a URL arg. How did we not see this before? Solved by making 'fulltext' the default search type.
