@subsection Including related messages
|
||||
@anchor{Including related messages}
|
||||
|
||||
It can be useful to include @emph{related} messages in your search results --
|
||||
that is, messages that belong to the message threads that one or more of the
|
||||
matched messages belong to, too. With this option, results are somewhat like
|
||||
the discussion threads in Gmail.
|
||||
|
||||
To enable this, set @code{mu4e-headers-include-related} to @code{t}. Since
|
||||
this can significanlty affect performance when there are many results,
|
||||
@code{mu4e-headers-include-related} is automatically disabled (for the next
|
||||
query) when the @code{mu4e-headers-results-limit} exceeds
|
||||
@code{mu4e-headers-include-related-maxnum}.
|
||||
It can be useful to not only show the messages that directly match a certain
|
||||
query, but also include messages that are related to these messages. That is,
|
||||
messages that belong to the same discussion thread are included in the
|
||||
results, just like e.g. Gmail does it. You can enable this behavior by setting
|
||||
@code{mu4e-headers-include-related} to @code{t}, and you can toggle between
|
||||
including/not-including with @key{W}.
|
||||
|
||||
@subsection Skipping duplicates
|
||||
@anchor{Skipping duplicates}
|
||||
|
||||
It is possible to show only one of multiple, duplicate messages (messages with
|
||||
the same Message-ID). This can be useful when you have copies of the same
|
||||
message, which is a common case, for example, when using Gmail and
|
||||
@t{offlineimap}.
|
||||
Another useful features is skipping duplicate messages. When you have copies
|
||||
of messages, there's usually little value in including more than one in search
|
||||
results. A common reason for having multiple copies of messages in the
|
||||
combination of Gmail and @t{offlineimap}, since that is the way the labels /
|
||||
virtual folders in Gmail are represented. You can enable skipping duplicates
|
||||
by setting @code{mu4e-headers-skip-duplicates} to @code{t}, and you can toggle
|
||||
between the skipping/not skipping with @key{V}.
|
||||
|
||||
To skip duplicates, set @code{mu4e-headers-skip-duplicates} to @code{t}.
|
||||
Note, messages are considered duplicates when they have the same
|
||||
@t{Message-Id}.
