Splunk ES Proxy Log Query Explanation Needed Regarding xswhere and "is above high"

[tegosa]

I can not find anything in the docs regarding "xswhere" and this "is above high"
Here is the query :
| tstats allow_old_summaries=true count as web_event_count from datamodel=Web by Web.src, Web.http_method | drop_dm_object_name("Web") | xswhere web_event_count FROM count_by_http_method_by_src_1d in web by http_method is above high

Any help would be appreciated thanks.
