To reindex all indexers we have the index:reindex:all command.
In some cases it’s only needed to reindex only some indexers.
Since version 1.75.0 you can specify the indexer by code if you run pass index codes direct as argument:
$ n98-magerun.phar index:reindex catalog_product_attribute,tag_summary
If you don’t know the indexer code or if you are lazy you can run the index:reindex command without any argument.
If the index prompt asks you to select an indexer you can enter multiple indexer numbers seperated by a comma.
Reindex  catalog_product_attribute (last runtime: 0)  catalog_product_price (last runtime: 0)  catalog_url (last runtime: 0)  catalog_product_flat (last runtime: 4s)  catalog_category_flat (last runtime: 0)  catalog_category_product (last runtime: 0)  catalogsearch_fulltext (last runtime: 1s)  cataloginventory_stock (last runtime: 0)  catalogpermissions (last runtime: 0)  targetrule (last runtime: 0) Please select a indexer:1,7
This would start reindexing for “catalog_product_attribute” and “catalogsearch_fulltext”.
I hope you safe some time to drink a coffee. If it’s so let me head from you or leave a comment in our blog.
