# 1. Get rid of ambiguity in parameters, you pass in user_parameters, from the BL rails app. No 
# need to pass in direct solr parameters, the caller can add them on themselves, eg: 
# i_want_to_force = {:rows => "10000"}
#   solr_search_params(params).merge(i_want_to_force)
#
# 2. Try to make it as easy as possible to add units of logic and remove/replace units of logic
# -- we do that a lot.  This may may be 'too clever', but the analogy is before_filter on 
# controller, remember "before_filter :method_name", this is a similar thing for mapping logic.

<%= form_tag ... do %>
  <span>something</span>
  <%= not_html_safe %>
<% end %>


That ends up making the entire block inside the form_tag do html escaped, which ordinarily isn't what happens in a view, but since it's inside a 'do' block, it does.

...which is why it's important for helper methods that return html to .html_safe it BEFORE they return it, like Rails own helpers do.
