Recently I ran into a problem regarding Re-index in Magento.
My store has around 40,000 products and If I change a status of a single product, changes are not reflected on frontend as it needs reindexing of all Indexes.
Moreoever reindexing takes a hell lot of time (around an hour) and I am thinking of a permanent issue.
What does "Save on Update" mode in Reindex specifies ? Does it help in reindexing while saving the product ?
Whats the difference between manual update and update on save ?
Please help.
Thanks in advance.
Use the "Update On Save" re-indexing mode, it will do re-index on the fly for that single product you have saved.
