[4] If there is no delineation you can use parse: Syslog. | parse SyslogMessage with * "Before_Text" NewColumnName"After_Text" *.

The dcount() aggregation function is primarily useful for estimating the cardinality of huge sets. It trades accuracy for performance, and may return a result that varies between executions. The order of inputs may have an effect on its output. This function is used in conjunction with the summarize operator.

This issue is a placeholder for adding support directly in KQL for fuzzy queries. The syntax may not remain the same, but the concept & functionality would.
