Reactjs 如何从 graphqlapollo 中的缓存中清除多个查询

我正在开发一个基于GraphQL/Apollo/Reaction的网络. 所以我想使用Mutation来发出POST请求，当完成时，我清理了一些针对某些查询的缓存.我读了Apollo的doc，它指导我如何从缓存和写操作中读取数据. 但我有三个问题:

1. 我可以用一个客户端.ReadQuery调用读取多个查询缓存吗？如果答案是否定的，那么ReQuery是否同步执行？
2. 如何在读取后清除查询缓存(而不是更新)？
3. 查询的缓存更新或重新获取(Refetch In UseMutation)是否会强制重新呈现调用该查询的所有组件？

我的样例代码如下:

 import type {DataProxy, FetchResult} from 'react-apollo'
 import {useMutation} from '@apollo/react-hooks'
  
 const[theMutationQuery] =  useMutation(MUTATIONQUERY, {
   refetchQueries: [somequery expression] // will the force a rerender of all components that use 'somequery'
   onCompleted: () => {},
   onError: () => {},
   update: (store: DataProxy, data: FetchResult<?*>) => { 
      const cacheDataForOtherQuery = store.readQuery({
           query: GETQUERY1
           variables: { 
              v: "str",
           },
           // so can i add one more query here?
     }) 
     // then how should I clean up the result from readquery, that is, cacheDataForQuery. Also, after cleaning up, will this force a rerender of all components using the query(GETQUERY1 here)
   }
 });
