Some of the SOLR query examples in event index design documents contain syntax errors and incorrect field names.
The affected documents are:
http://mule1.dataone.org/ArchitectureDocs-current/design/LogAggregator.html and http://mule1.dataone.org/ArchitectureDocs-current/design/UsageStatistics.html

The correct endpoint for the logsolr service is 'https://cn.dataone.org/cn/v1/query/logsolr', not 'https://cn.dataone.org/cn/v1/query/logsolr'. The latter endpoint
causes the v1 'log' service to handle the request.

Some of the queries use incorrect field names, such as 'datetime' instead of 'dateLogged'. Some of the field queries use the wildcard character '' at the beginning of the
search term (e.g. &fq=*eml, which causes a syntax error.

Also, some of the queries select or facet on protected fields, e.g. 'subject' and it should be clearly indicated that queries using protected fields are subject to filtering according
to the DataONE authentication mechanism. This is alluded to in the 'Event Log Index' table in UsageStatistics.html and mentioned elsewhere in this document, but maybe needs
to be mentioned in the examples also.
