Quick navigation to pages with spaces in doesn't work

[csmith]

The query selector here:

                        searchForm.addEventListener('submit', function (e) {
                          e.preventDefault()
                          if (searchList.querySelector('[value=' + searchInput.value + ']')) {
                            document.location.href = '/view/' + searchInput.value
                          } else {
                            document.location.href = '/wiki/search?pattern=' + searchInput.value
                          }
                        })

doesn't cope with spaces in the search term
