Search details
The search function is optimized for searching a large number of messages.
However, this can lead to unexpected search results. Keep in mind the following
when analyzing search results:
Note: If any term in the search phrase matches 50% or more of the messages in
the database, then the search will show no results.
■
About 570 common words such as “after” and “which” are ignored in any of
the search boxes, as well as the word “spam.” These are called MySQL
stopwords.
■
Words of three characters or less are ignored. This applies to To, From,
Subject, and Message ID searches.
■
If any word in a multiple word search is found in a message, that message is
considered a match. For example, searching for “red carpet” will match “red
carpet,” and also “red wine” and “flying carpet.” You don’t have to put quote
marks around search text that contains spaces.
■
Searches match exact whole words only in To, From, Subject, and Message
ID searches. A word is considered a group of letters, numbers, or
underscores. For example, if you searched for “finance”, the search would
not find “refinance.” Also, if you searched for “user_name@example.com”,
the search is interpreted as “user_name” OR “example”. Since “com” is three
characters, it is ignored. The @ and the period are treated as spaces.
■
Search results are sorted by date descending order by default but can be
resorted by clicking on a column heading.
■
Wildcards such as * are not supported in search. All searches are literal.
■
If you search for multiple characteristics, only messages that match the
combination of characteristics are listed in the search results. For example,
if you typed “LPQTech” in the From box and “Inkjet” in the Subject box, only
messages containing “LPQTech” in the From header and “Inkjet” in the
Subject:
header would be listed in the search results.
■
All text searches are case-insensitive. This means that if you typed emerson
in the From box, then messages with a
From:
header containing emerson,
Emerson, and eMERSOn would all be displayed in the search results.
