Find posts in mxCalendar via SimpleSearch

I have installed ModX Revo 2.3.2, SimpleSearch and mxCalendar.

When i search with SimpleSearch there are no results from posts of mxCalendar.
How is it possible to find post of mxCalendar via SimpleSearch?

SimpleSearch needs to be told to search the mxcalendar_events db table (I think it only searches site_content by default).

http://rtfm.modx.com/extras/revo/simplesearch/simplesearch.simplesearch and scroll down to "Search Custom Tables"

you will need to create a custom search-driver, which searches also mxCalendar (or perhaps migxCalendars) - entries.

Another option could be, to have installed a solr-server, index resources and calendar-entries into solr and use a
solr - search - driver for searching both at the same time.

Thank you for the fast answers. I will test it an give you a feedback.
