What is the purpose of an indexTags setting of Group\:Work

You should never include backslashes when entering property values. MinimServer automatically adds backslashes to the config file when these are required.

Perhaps I have misunderstood what you posted. Was it a copy-and-paste extract from the config file or was it the output from the props command? If it was the latter, everything is fine except that you should remove the backslash in Group\:Work.
