[Pedro Casado]

• Symfony version: 3.4.26
• Algolia Search Bundle version: 3.4.0
• Algolia Client Version: 1.28.0
• Language Version: php7.2

Description

The search:clear command doesnt consider prefix on index name.

Steps To Reproduce

• Create an index called prod_product
• Create an entity Product
• Setup bundle

algolia_search:
    prefix: prod
    indices:
        - name: product
          class: AppBundle\Entity\Product
          enable_serializer_groups: true

• Run task

$ ./bin/console search:clear --env=prod
```

Result:

```
Index product  couldn't be cleared
Done!

Index name should consider prefix and be prod_product

[Pedro Casado]

Specifying the -i option it does clear the correct index.

./bin/console search:clear --env=prod -i product

The result should be the correct index name (prod_product), but thats ok.

Cleared product index of AppBundle\Entity\Product
Done!
