    The patch below will display the layered navigation in Advanced search result and will work fine with layered navigations. The layered navigation and search result are displayed based on two separate product collections, one created by catalogsearch/Model/Layer.php and the other by catalogsearch/Model/Advanced.php. So we need to override few functions of both these models to make layered nav work in Advanced search.

    1- In your local.xml under catalogsearch_advanced_result tag add.

     <reference name="left">
          <block type="catalogsearch/layer" name="catalogsearch.leftnav" after="currency" template="catalog/layer/view.phtml"/>
     </reference>
    

    Override prepareProductCollection function of catalogsearch/model/Layer.php with

    public function prepareProductCollection($collection){
    
        if(Mage::helper('catalogsearch')->getQuery()->getQueryText())//for normal search we get the value from query string q=searchtext
            return parent::prepareProductCollection($collection);
        else{
    
            $collection->addAttributeToSelect(Mage::getSingleton('catalog/config')->getProductAttributes());
            /**
             * make sure you cross check the $_REQUEST with $attributes
             */
            $attributes = Mage::getSingleton('catalog/product')->getAttributes();
    
            Mage::log(print_r($_REQUEST,1));
            foreach($attributes as $attribute){
                $attribute_code = $attribute->getAttributeCode();
                //Mage::log("--->>". $attribute_code);
                if($attribute_code == "price")//since i am not using price attribute
                    continue;
    
                if (empty($_REQUEST[$attribute_code])){
                    //Mage::log("nothing found--> $attribute_code");
                    continue;
                }
                if(!empty($_REQUEST[$attribute_code]) && is_array($_REQUEST[$attribute_code]))
                    $collection->addAttributeToFilter($attribute_code, array('in' => $_REQUEST[$attribute_code]));
                else
                if(!empty($_REQUEST[$attribute_code]))
                    $collection->addAttributeToFilter($attribute_code, array('like' => "%" . $_REQUEST[$attribute_code] . "%"));
            }
    
            $collection->setStore(Mage::app()->getStore())
            ->addMinimalPrice()
            ->addFinalPrice()
            ->addTaxPercents()
            ->addStoreFilter()
            ->addUrlRewrite();
    
            //Mage::log($collection->getSelect()->__toString());
    
            Mage::getSingleton('catalogsearch/advanced')->prepareProductCollection($collection);    
            Mage::getSingleton('catalog/product_status')->addVisibleFilterToCollection($collection);
            Mage::getSingleton('catalog/product_visibility')->addVisibleInSearchFilterToCollection($collection);
        }
    
        return $this;
    }
    

    Override getProductCollection, getSearchCriterias function of catalogsearch/model/Advanced.php with

    public function getProductCollection(){
    
        if (is_null($this->_productCollection)) {
            $this->_productCollection = Mage::getResourceModel('catalogsearch/advanced_collection')
                ->addAttributeToSelect(Mage::getSingleton('catalog/config')->getProductAttributes())
                ->addMinimalPrice()
                ->addStoreFilter();
                Mage::getSingleton('catalog/product_status')->addVisibleFilterToCollection($this->_productCollection);
                Mage::getSingleton('catalog/product_visibility')->addVisibleInSearchFilterToCollection($this->_productCollection);
    
            if(isset($_GET['cat']) && is_numeric($_GET['cat'])) 
                $this->_productCollection->addCategoryFilter(Mage::getModel('catalog/category')->load($_GET['cat']),true);
        }
        return $this->_productCollection;
    }
    
    public function getSearchCriterias()
    {
        $search = parent::getSearchCriterias();
        /* display category filtering criteria */
        if(isset($_GET['cat']) && is_numeric($_GET['cat'])) {
            $category = Mage::getModel('catalog/category')->load($_GET['cat']);
            $search[] = array('name'=>'Category','value'=>$category->getName());
        }
        return $search;
    }

    There is no quick solution for this. The standard search and the advanced search use two different methods to search.

    If you compare the layouts in catalogsearch.xml you see that for catalogsearch_advanced_result the block catalogsearch/layer is not included. If you copy the block definition from catalogsearch_result_index and change the root template to 3columns.phtml various errors are thrown.

    In my 1.6.2 the layered nav showed up after setting a 0 (Zero) to
    System -> Configuration -> Catalog -> Catalog Search -> Apply Layered Navigation if Search Results are Less Than

    Simply adding following line in catalogsearch.xml advance search results left area helped me to get it visible on my EE site, however I haven't checked it in CE version.

    <block type="catalogsearch/layer" name="catalogsearch.leftnav" before="-" template="catalog/layer/view.phtml"/>
    

    So my full left area looks like this on advance search area on xml file:

    <reference name="left">
           <block type="catalog/navigation" name="hello.leftnav" as="hello.leftnav" template="catalog/navigation/hello_left_nav-search.phtml" />
            <block type="catalog/layer_view" name="catalog.leftnav" before="-" template="catalog/layer/view.phtml"/>
        </reference>
    

    Hope it helps others.

    This link goes to Magento website should help. You need to create attributes from Catalogues. Then see the settings under Frontend Properties (Catalogues>Attributes).
