+::: tip Tip
+
+For the parameter **filter**, the `filter` parameter in the URL should be split into a string by `,`, here is an example.
+
+In <https://pubmed.ncbi.nlm.nih.gov/trending/?filter=simsearch1.fha&filter=pubt.clinicaltrial&filter=pubt.randomizedcontrolledtrial>, the filter parameters are `simsearch1.fha`, `pubt.clinicaltrial`, and `pubt.randomizedcontrolledtrial`. Therefore, the filter corresponding to the route should be filled with `simsearch1.fha,pubt.clinicaltrial,pubt.randomizedcontrolledtrial`, and the route is [`/pubmed/trending/simsearch1.fha,pubt .clinicaltrial,pubt.randomizedcontrolledtrial`](https://rsshub.app/pubmed/trending/simsearch1.fha,pubt.clinicaltrial,pubt.randomizedcontrolledtrial)

+
+::: tip 提示
+
+对于参数 **过滤条件**，应将 URL 中的 filter 参数用 `,` 分割成一个字段填入，下面是一个例子。
+
+<https://pubmed.ncbi.nlm.nih.gov/trending/?filter=simsearch1.fha&filter=pubt.clinicaltrial&filter=pubt.randomizedcontrolledtrial> 中 filter 参数有 `simsearch1.fha` `pubt.clinicaltrial` `pubt.randomizedcontrolledtrial` 三者。所以，对应到路由的 filter 应填入 `simsearch1.fha,pubt.clinicaltrial,pubt.randomizedcontrolledtrial`，于是可获得路由 [`/pubmed/trending/simsearch1.fha,pubt.clinicaltrial,pubt.randomizedcontrolledtrial`](https://rsshub.app/pubmed/trending/simsearch1.fha,pubt.clinicaltrial,pubt.randomizedcontrolledtrial)
