Magento - Website/Store level indexing

Question

We are working on Magento 1.7.0.2 (community). We have created multiple websites. Our query is, is there way to indexing on selected website or store? like website or store level configuration.

Consider the the scenario, we have 3 website (WEBSITE1, WEBSITE2, WEBSITE3) and 3 store (STORE1, STORE1, STORE1) 1. If we update WEBSITE1 and STORE1 then indexing will only for WEBSITE1 and STORE1. 2. If we update WEBSITE2 and STORE2 then indexing will only for WEBSITE2 and STORE2. 3. If we update WEBSITE3 and STORE3 then indexing will only for WEBSITE3 and STORE3.

Please help us.

Answer 1

You can try this.

<?php
$mageFilename = 'app/Mage.php';
require_once $mageFilename;
umask(0);

// clean overall cache Mage::app()->cleanCache();
echo "Cache Cleaned!<br/>\n";

// clear 'refresh_layered_navigation'
$storeid = Mage::app()->getRequest()->getParam('storeid');

// Only process if a storeid is passed
if ($storeid) {
  $store = Mage::app()->getStore($storeid);
  Mage::getSingleton('catalogindex/indexer')->plainReindex(null, null, $store); 
  echo 'Layered Navigation Indices was refreshed succesfuly for Store Id: '.$storeid.'<br>';
}
?>

Yes, the indexes are like a data warehouse as Anshu described. But depending on the index it is on website or store level, how else do you want to have the correct prices or translations for the products?

I'm not sure what you want to achieve. Indexing all products in one store? Or one website? This is not possible out of the box. Magento supports two ways of indexing: One product/item or all.

e.g.

\Mage_Bundle_Model_Resource_Indexer_Price::reindexAll
\Mage_Bundle_Model_Resource_Indexer_Price::reindexEntity

So it should be easy possible to implement you own indexer which does this, hopefully? :-) But magento has afaik no logic either to save WHICH store/website data needs to be reindexed.
