Azure announced the ability to upgrade Azure Log Analytics workspace recently. It comes with a new query language (https://docs.loganalytics.io/index). But after the upgrade their Search REST API (https://docs.microsoft.com/en-us/azure/log-analytics/log-analytics-log-search-api) isn't working anymore. I wasn't able to find a way to execute new Search Queries via REST. I would imagine that it would be similar to AppInsights API (https://dev.applicationinsights.io/).
It also seems like they have actual API but no documentation as of yet, because Microsoft Flow has ability to integrate and execute Search Queries with the upgraded workspace (https://docs.microsoft.com/en-us/azure/log-analytics/log-analytics-flow-tutorial).
Any help in pointing on how to execute new Search API via REST is greatly appreciated.
Thanks
