| 1975 | - | |
| 1976 | -Elasticsearch 6 removes the ability to reindex with the `_all` field. Before you upgrade, we recommend disabling this field manually and specifying default fields on your models. | |

| 1978 | -```ruby | |
| 1979 | -class Product < ApplicationRecord | |
| 1980 | - searchkick _all: false, default_fields: [:name] | |
| 1981 | -end | |
| 1982 | -``` | |
| 1983 | - | |
| 1984 | -If you need search across multiple fields, we recommend creating a similar field in your search data. | |
