.SH "SEARCH SYNTAX"
for a mail to be selected.
.TP
-\fBf <regexp>\fR selects mails whose field From, From:, or Reply-To: matches the regexp. Since the initial "From " line contains the date, this search criterion can be used to restrict to a certain year or month.
+\fBf <regexp>\fR (from) selects mails whose leading line From, or
+fields From:, or Reply-To: matches the regexp.
+.TP
+\fBt <regexp>\fR (to) selects mails whose field To:, Cc:, or Bcc: matches the regexp.
.TP
-\fBt <regexp>\fR selects mails whose field To:, Cc:, or Bcc: matches the regexp.
+\fBp <regexp>\fR (participant) selects mails whose leading line From,
+or fields From:, Reply-To:, To:, Cc:, or Bcc: matches the regexp.
.TP
-\fBp <regexp>\fR selects mails whose field From, From:, Reply-To:, To:, Cc:, or Bcc: matches the regexp.
+\fBs <regexp>\fR (subject) selects mails whose field Subject: matches the regexp.
.TP

.TP
-\fBd <regexp>\fR selects mails whose field Date: matches the regexp.
+\fBb <regexp>\fR (body) selects mails whose body matches the
+regexp. This needs to read fully the original mboxes and can take a
+long time. Other conditions have to be fulfilled before the body is
+read though.
