NAME
Mail::Box::Search - select messages within a mail box
INHERITANCE
Mail::Box::Search
is a Mail::Reporter
Mail::Box::Search is extended by
Mail::Box::Search::Grep
Mail::Box::Search::SpamAssassin
Mail::Server::IMAP4::Search
SYNOPSIS
use Mail::Box::Manager;
my $mgr = Mail::Box::Manager->new;
my $folder = $mgr->open('Inbox');
my $filter = Mail::Box::Search::[something]->new;
my @msgs = $filter->search($folder, ...);
if($filter->search($message)) {...}
DESCRIPTION
This "Mail::Box::Search" class is the base class for various message scan algorithms. The
selected messages can be labeled. Boolean operations on messages are supported.
Currently implemented searches:
Mail::Box::Search::Grep
Match header or body against a regular expression in a UNIX "grep" like fashion.
Mail::Box::Search::SpamAssassin
Try to detect spam, using Mail::SpamAssassin.
Mail::Box::Search::IMAP
Search an IMAP folder for special interface IMAP folders provide for it. UNDER
CONSTRUCTION till Mail::Transport::IMAP4 is complete.
Extends "DESCRIPTION" in Mail::Reporter.

Mail::Box::Search->new(%options)
Create a filter.
-Option --Defined in --Default
binaries <false>
decode <true>
delayed <true>
deleted <false>
deliver undef
in 'BODY'
label undef
limit 0
log Mail::Reporter 'WARNINGS'
logical 'REPLACE'
multiparts <true>
trace Mail::Reporter 'WARNINGS'
binaries => BOOLEAN
Whether to include binary bodies in the search.
decode => BOOLEAN
Decode the messages before the search takes place. Even plain text messages can be
encoded, for instance as "quoted-printable", which may disturb the results.
However, decoding will slow-down the search.
delayed => BOOLEAN
Include the delayed messages (which will be parsed) in the search. If you set this
to false, you may find fewer hits.
deleted => BOOLEAN
In most cases, you will not be interested in results which are found in messages
flagged to be deleted. However, with this option you can specify you want them to
be searched too.
deliver => undef|CODE|'DELETE'
The exact functionality of this parameter differs per search method, so read the
applicable man-page. In any case "undef" means that details are not collected for
this search, which is the fastest search.
"DELETE" will flag the message to be flagged for deletion. You may also specify
your own CODE reference. With an reference to an array, the information about the
matches is collected as a list of hashes, one hash per match.
in => 'HEAD'|'BODY'|'MESSAGE'
Where to look for the match.
label => STRING
Mark all selected messages with the specified STRING. If this field is not
specified, the message will not get a label; search() also returns a list of
selected messages.
limit => NUMBER
Limit the search to the specified NUMBER of messages. When the NUMBER is positive,
the search starts at the first message in the folder or thread. A negative NUMBER
starts at the end of the folder. If the limit is set to zero, there is no limit.
log => LEVEL
logical => 'REPLACE'|'AND'|'OR'|'NOT'|'AND NOT'|'OR NOT'
Only applicable in combination with a "label". How to handle the existing labels.
In case of "REPLACE", messages which already are carrying the label are stripped
from their selection (unless they match again). With "AND", the message must be
selected by this search and already carry the label, otherwise the label will not be
set. Specify "OR" to have newly selected messages added to the set of already
selected messages.
"NOT" is true for messages which do not fulfil the search. The details output will
still contain the places where the match was found, however those messages will
complementary set of messages will be labeled and returned.
multiparts => BOOLEAN
Are multiparts to be included in the search results? Some MUA have problems
handling details received from the search. When this flag is turned off, the body
of multiparts will be ignored. The parts search will include the preamble and
epilogue.
trace => LEVEL
Searching
$obj->inBody($part, $body)
Tests whether body contains the requesting information. See the specific search
module for its parameters.
$obj->inHead($part, $head)
Tests whether header contains the requesting information. See the specific search
module for its parameters.
$obj->search($folder|$thread|$message|ARRAY)
Check which messages from the $folder (Mail::Box) match the search parameters. The
matched messages are returned as list. You can also specify a $thread (a
Mail::Box::Thread::Node), one single $message (a Mail::Message), or an ARRAY of
messages.
Sometimes we know how only one match is needed. In this case, this searching will
stop at the first match. For instance, when "limit" is "-1" or 1, or when the search
in done in scalar context.
example:
my $grep = Mail::Box::Search::Grep->new
( match => 'My Name Is Nobody'
, deliver => 'PRINT'
);
$grep->search($folder);
my $message = $folder->message(3);
$grep->search($message);
my $thread = $message->threadStart;
$grep->search($thread);
$obj->searchPart($part)
Search this message $part for matches.
The Results
$obj->printMatch( [$fh], HASH )
Print the information about the match (see new(deliver)) in some understandable way.
If no file handle is specified, the output will go to the selected filehandle (see
"perldoc -f select").

DIAGNOSTICS
Error: Cannot search in body.
Th search object does not implement inBody(), and can therefore not search a message
body.
Error: Cannot search in header.
Th search object does not implement inHead(), and can therefore not search a message
header.
Error: Don't know how to deliver via results in $way.
The search results cannot be delivered in the specific way, because that is not a
defined alternative.
Error: Package $package does not implement $method.
Fatal error: the specific package (or one of its superclasses) does not implement this
method where it should. This message means that some other related classes do
implement this method however the class at hand does not. Probably you should
investigate this and probably inform the author of the package.
Error: Search in BODY, HEAD or MESSAGE not $in.
The "in" option defines only three names.
