preview is still present here, opp_link just provides extra params (and should be renamed to search_params or something like that so it's less confusing. This could work instead w/o removing the link to the item
```ruby
<%= link_to opportunity_path(preview, (opp_link || {})) do %>
  <h3 class='name'><%= truncate(preview.position_title, :length => 40) %></h3>
<% end %>
```
