When I add a specific subcategory to my query string on my search results page I can see the chosen refinements list and filter options for other categories, price ranges, etc. However if I only do a keyword search I do not see any filter options. How can I set my results page to show all available filters with just a keyword search?
Edited to add - here is the layout xml:
<catalogsearch_result_index translate="label">
<label>Quick Search Form</label>
<update handle="page_two_columns_left" />
<reference name="root">
<action method="setTemplate"><template>page/1column.phtml</template></action>
</reference>
<reference name="left">
</reference>
<reference name="content">
<block type="catalogsearch/layer" name="catalogsearch.leftnav" after="currency" template="catalog/layer/view.phtml"/>
<block type="catalogsearch/result" name="search.result" template="catalogsearch/result.phtml">
<block type="catalog/product_list" name="search_result_list" template="catalog/product/list.phtml">
<block type="catalog/layer_view" name="filter" template="catalog/layer/view.phtml"/>
<block type="catalog/product_list_toolbar" name="product_list_toolbar" template="catalog/product/list/toolbar.phtml">
<block type="page/html_pager" name="product_list_toolbar_pager"/>
</block>
<action method="setColumnCount"><count>3</count></action>
<action method="addColumnCountLayoutDepend"><layout>empty</layout><count>6</count></action>
<action method="addColumnCountLayoutDepend"><layout>one_column</layout><count>5</count></action>
<action method="addColumnCountLayoutDepend"><layout>two_columns_left</layout><count>4</count></action>
<action method="addColumnCountLayoutDepend"><layout>two_columns_right</layout><count>4</count></action>
<action method="addColumnCountLayoutDepend"><layout>three_columns</layout><count>3</count></action>
<action method="setToolbarBlockName"><name>product_list_toolbar</name></action>
</block>
<action method="setListOrders"/>
<action method="setListModes"/>
<action method="setListCollection"/>
</block>
</reference>
</catalogsearch_result_index>
Here is a screen shot of the page prior to any filters on the search:
