* The function_score allows you to modify the score of documents that are retrieved by a query. This can be useful if, |
|
10
|
|
|
* for example, a score function is computationally expensive and it is sufficient to compute the score on a filtered |
|
11
|
|
|
* set of documents. |
|
12
|
|
|
* |
|
13
|
|
|
* To use function_score, the user has to define a query and one or more functions, that compute a new score for each |
|
14
|
|
|
* document returned by the query. |

Duplicated code is one of the most pungent code smells. If you need to duplicate the same code in three or more different places, we strongly encourage you to look into extracting the code into a single class or operation.
You can also find more detailed suggestions in the “Code” section of your repository.
