Generally speaking, if your `SolrClient` will only be used on a single core/collection, including that entity in the path is the most convenient. Where more flexibility is required, the collection/core should be excluded.
==== Base URLs of Http2SolrClient
Since `Http2SolrClient` can manages connections to different nodes efficiently. `Http2SolrClient`
does not require a `baseUrl`. In case of `baseUrl` is not provided, `SolrRequest.basePath` must be set, so
`Http2SolrClient` can know which node it will request to. If not an `IllegalArgumentException` will be thrown.

timeout that allows requests to non-responsive nodes to fail quicker than waiting for a socket timeout.
The default value of this timeout is set to 15000 ms and can be adjusted by a system property `solr.cloud.client.stallTime`.
This value should be smaller than `solr.jetty.http.idleTimeout` (Which is 120000 ms by default) and greater than the
