Dependencies:
-------------

  * SilvaFind 1.0 depends on Silva-1.6 or later.

Installation instructions:
--------------------------

  * Fresh install

    Put SilvaFind into your Products folder and restart zope. When you create a
    fresh Silva Root, everything will be setup automaticly. You will have a
    Silva Find instance called 'search' in your Site Root.

  * Upgrade

    Put SilvaFind into your Products folder, restart zope, and install Silva
    Find in the Service Extensions. (If you have an existing Silva Find
    installed, click the refresh button in silva_extensions.) Now you should be
    able to add a "Silva Find" object in the select dropdown box of the Silva
    contents screen. If not, go to the "properties" screen, then click on
    "addables" and check the checkbox next to Silva Find.
    
    When a user is in a Silva Find content type, an extra stylesheet is called
    to style the search results. This CSS is located in:
    
    http://[yourSilva]/service_resources/SilvaFind/search.css
    
    In order to call the CSS, there needs to be a check for the metatype
    included in your layout. Add the following code within the <head> section
    of your layout_macro, after the stylesheet links:
    
    <!-- Injector for content-specific css/js inclusion -->
    <link tal:replace="structure here/head_inject | nothing" />
    
    This calls a (new) page template called 'head_inject'. To install it, you
    can reinstall the layout templates as explained here:
    
    http://infrae.com/products/silva/docs/manager/ZMI_Silva#ZMI__Layout_templates
    
    This will install all the templates including the new head_inject page
    template. You can delete all the 'default_*'s that appeared.
    
    Now the Silva Find result pages should include the search stylesheet.
    
  * Customization
    
    If you want to modify the search.css, you can copy its selectors and change
    the head_inject to call yourSearch.css. Don't modify the search.css on the
    file system in service_resources, as it should be overwritten in an upgrade.
    
  * Silva Layout extension users
    
    If you're using the new Five-based Silva Layout you'll need to add
    the above link tag to your main and possibly other templates.
        
  * Creating a head_inject manually
    
    You can skip installing the layout templates and create a page template
    called 'head_inject' in your Silva root with the following code:
    
<tal:comment replace="nothing">
  define a model variable that works in public and smi preview skins
</tal:comment>
<tal:block tal:define="model request/model|here">
<tal:block tal:condition="python:model.meta_type == 'Silva Find'">
  <tal:comment replace="nothing">
    load custom styles for search form and search results
    if we're viewing a Silva Find instance
  </tal:comment>
  <link rel="stylesheet" type="text/css" media="all"
    tal:define="metatypecss here/service_resources/SilvaFind/search.css/absolute_url | nothing"
    tal:condition="metatypecss"
    tal:attributes="href metatypecss" />
  <tal:comment replace="nothing">
    Make sure search results are never cached.
  </tal:comment>
  <tal:block replace="structure model/@@set_nocache" />
</tal:block></tal:block>
    
    Note that extension developers can use this to call specific css files for
    special content types. Modify the head_inject to check for your metatypes
    too. However, in the Five-based future, extensions will control their own
    views and this metatype checking won't be necessary.
