Ruby on Rails: Search Form - multiple search fields

I am trying to create an application that allows the user to search a database. The search page layout would behave with some drop down menus that would show data already in the database to narrow the search, and also text boxes to allow the user to put in key words like the "project name". I'm having a problem getting rails to take all the info that has been entered in the search form, and performing one big search.

Here is part of my search layout:

    <%= form_tag search_path, :method => 'get' do %>

  <%= hidden_field_tag :direction, params[:direction] %>      <%= hidden_field_tag :sort, params[:sort] %>     <p>     <%= text_field_tag :search, params[:search] %>     <%= submit_tag "Search Project Name", :project_name => nil %>     </p>     <p>     <%= text_field_tag :search, params[:search] %>     <%= submit_tag "Search Client", :client => nil %>     </p>     <% end %>

Here is my index and search actions in the project controller:

    def index   @projects = Project.all

    respond_to do |format|       format.html # index.html.erb       format.json { render :json => @projects }      end     end

    def search

    @project_search =[:search]).order(sort_column + ' ' + sort_direction).paginate(:per_page => 5, :page => params[:page])


and here is part of my models/project.rb file

    def     if search       where('project_name LIKE ?', "%#{search}%") || where('client LIKE ?', "%#{search}%")     else       scoped     end     end

As you can see, I am just trying to search on either the project_name or the client. If I can get this working, I will be extending it onto other fields.

The functionality at the moment is that, when I try to search it both boxes, it overwrites one, and only does one of the field searches.

I am new to ROR so hopefully someone can help. Any suggestions will be appreciated.

Thanks in advance!

I have not looked at your code in detail but if you have a look at the Rails Guide on Debugging you will find techniques that can help you debug your code.
