# `JSONAPIPlug.QueryParser.Filter`
[🔗](https://github.com/lucacorti/jsonapi_plug/blob/main/lib/jsonapi_plug/query_parser/filter.ex#L1)

JSON:API 'filter' query parameter parser

Since the specification does not define the format for the [JSON:API filter](http://jsonapi.org/format/#fetching-filtering)
parameter, the default implementation just returns the value of 'filter' as is.
