Magento mini-search box
By default, mini-search box is placed in the header section.
To change mini-search box’s placement to left or right column, simply change <reference name="header">
to <reference name="left"> (or "right") in catalogsearch.xml
<reference name="header">
<block type="core/template" name="top.search" as="topSearch" template="catalogsearch/form.mini.phtml"/>
</reference>
To place the mini-search box above everything on the left column, simply add a before=”-” in the above code. Note that in order for before=”-” works throughout the site, it cannot be declared somewhere else in the same column.
Example: In the Magento Default Theme, before=”-” is declared in the right column under the <default> for mini-cart in the checkout.xml. Then in catalog.xml it gets declared again for related product in <catalog_product_view> section.
With two before=”-” being declared, on the front-end Any other pages except product page, you will be seeing mini-cart block except the Product View page.
