compound search (content: with AND)

[DBU]

trying to figure out why this WORKS:
ext:.docx parent:D:\Documents content:longer content:user content:hourly

But, these FAIL:
ext:.docx parent:D:\Documents content:("longer" AND "user" AND "hourly")
ext:.docx parent:D:\Documents content:(longer AND user AND hourly)

I thot at least one of the last 2 is a good construct. thanks

Please use < and > for grouping:

ext:.docx parent:D:\Documents content:<"longer" "user" "hourly">

ext:.docx parent:D:\Documents content:<longer user hourly>

Space = AND
