"pycsw has the ability to perform distributed searching against other CSW "
"servers.  Distributed searching is disabled by default; to enable, ``server."
"federatedcatalogues`` must be set.  A CSW client must issue a GetRecords "
"request with ``csw:DistributedSearch`` specified, along with an optional "
"``hopCount`` attribute (see subclause 10.8.4.13 of the CSW specification).  "
"When enabled, pycsw will search all specified catalogues and return a "
"unified set of search results to the client.  Due to the distributed nature "
"of this functionality, requests will take extra time to process compared to "
"queries against the local repository."

"pycsw与其它CSW服务器不同的是，它有能力自己实现分布式搜索。此分布式搜索默认为"

"CSW客户端会发出一个 ``Getrecords`` 指定性请求 ``csw:DistributedSearch`` ，"
"以及一个可选的 ``hopCount`` 属性（见CSW规范中第10.8.4.13 ）。"
"当启用时，pycsw会搜索所有指定的目录并会将一组统一的搜索结果返回给客户端。"
"由于此功能的分布式性质，若要查询本地存储库，请求可能会需要更多的时间来处理。"
