Now you can consume Popularity endpoint and specify a section to which the retrieved articles should belong to. This can be used to populate a most popular list on Section fronts.

## How to Use

### SDK

`recommendationsByPopularity` admits one additional parameter, section, that can be used as follows (limit, section):

`clavis.recommendationsByPopularity(3, "sports")`

### API

Using Clavis API you can specify the section of the Popularity recommendations:

`/clavis/training/site/[sitename]/documents/recommendations?section=sports`

## Things to know

Clavis filters by “contains” rather than exact match “is equal to”. If you have a section called `/sports` for an article in Composer, you can filter by that section by just passing `sports` as the section.

Similarly, if the section in Composer is called `/sports/basketball/nba`, the articles belonging to that section will be included if you pass `sports` as the section.

For this example and in terms of regular expressions, the regular expression would be `/sports/`.
