Searching For Files
Searching for files in eMule usually means that
all servers in the server list are asked if they know another
client you has a file with the matching search keyword. The
servers themselves do not store any files, they just compile
a list of the connected clients files.
The advanced search function in eMule allows precise searches
for files in the network. The more accurate a search is done
the better it is since searches put a considerable load onto
the servers. Therefore eMule only finds max 201 individual
sources of any given search term
Search
o Name
This filed takes the term to search for. Multiple
keywords can be entered and eMule will displays only hits
with all the keywords in the filename. For more accurate and
flexible searches see the boolean search further down this
chapter.
This textbox has an auto-completing feature which stores previous
search entries. To clear this list press and hold CTRL or
ALT then press DEL. To deactivate this feature at all, see
UseAutocompletion in Preferences -> Preferences.ini.
o Type
Type can be used to filter the hits for specific group of
extensions. The type of download and their associated extensions
are given in the table below:
| All |
no filter |
| Archive |
.ace, .arj, .gz, .hqx, .lha, .rar, .sea, .sit, .tar,
.tgz, .uc2, .zip |

.rm, .rv, .vivo, .vob, .wmv |
o Method
Method is the way eMule searches. Also web based search engines
for the eMule network are available. The results of the web
searches will open in the browser.
| > |
Server
Only the server, the client is currently connected to
will be searched. |
| > |
Global (Server)
All servers from the server list are queried. Each server
is asked individually. The green bar at the bottom shows
the progress of the search. |
| > |
Kademlia
Searches all the Kademlia network for the given keywords.
The eD2k network, i.e. servers are not search with this
method. It may take some time until the search results
arrive. Should even a popular search expression yield
no results then the system's UDP Port is probably blocked
by a firewall or router. |
| > |
Jigle
(Web)
Web based search engine. The Match Keyword checkbox
forces Jigle to return only results which have the exact
search keyword as a single phrase in the filename. |
| > |
Jigle
This method offers direct access to the Jigle Database
from within eMule. |

Filter
o min size / max size
Min and max size is used to narrow the search according to
file size. Only hits are displayed which are either over a
entered min size or below the given max size. If no additional
unit abbreviation is entered file size is assumed in Mega
bytes.
| Unit |
Valid abbreviations |
| Bytes |
b | byte | bytes |
| KiloBytes |
k | kb | kbyte | kbytes |
| MegaBytes |
m | mb | mbyte | mbytes |
| GigaBytes |
g | gb | gbyte | gbytes |
Examples:
Min size = 200
without further unit specified, this will only return files
with a minimum size of 200 mega bytes
Max size = 1gb
file size must not exceed 1 giga byte
o Availability
Denotes the minimal number of sources for a single file one
individual server must have for the search term to be counted
as hit.
Note:
This filter does not respect the global availability but a
per server availability. Setting this value too high may result
in no hits as the servers might not have indexed files with
that many sources.
o Extension
Only files with the provided extension will be found. The
extension has to be entered without the trailing .
e.g. the extension avi will only find this file type.
Boolean Search
This function is used to create complex search queries using
the boolean operators NOT, AND, OR. These operators always
have to be entered in capital letters otherwise they are counted
as a normal search Keyword.
| > |
NOT
This operator is actually called NAND which means "and
not". The keyword following a NOT will be excluded,
i.e. no hit may contain this keyword. Highest precedence.
String: Keyword1 NOT Keyword2 |
| > |
AND
AND is the default operator if no operator is specified.
AND-linked searches must contain all entered keywords
in the resulting hits. Medium operator precedence.
String: Keyword1 AND Keyword2 (equals: Keyword1 Keyword2) |
| > |
OR
OR means that any of the entered keywords result in a
hit. OR has the lowest precedence
String: Keyword1 OR Keyword2 |
| Notes: |
| > |
Kademlia searches must always start with
a keyword having 3 or more letters. After the first keyword
there must not be any boolean operator apart from AND. |
| > |
Except for the web based search engine filedonkey
the boolean search may be combined with any method or
filter. |
| > |
The operators are evaluated according to
their mathematical precedence. NOT -> AND
-> OR. This precedence can be change by setting
( ) around the expression which has to be evaluated first. |
| > |
To mask the operators or ( ) quotation marks
" " can be used. Operators or ( ) enclosed in
" " will not be interpreted by their boolean
meaning but be used as normal search keywords. |
| > |
OR and NOT linked searches are not as restrictive
as AND searches. AND requires the whole keyword to match
whereas OR and NOT also allow partial matches in another
word. |
| > |
OR and NOT also take into account embedded
meta data like mp3 tags or comment / author information
of files. |
| |
|
| Examples: |
| > |
Search |
Keyword1 Keyword2 OR Keyword3
Keyword4 |
| |
Boolean interpretation |
(Keyword1 AND Keyword2) OR (Keyword3 AND
Keyword4) |
| |
Explanation |
Finds files that must contain either keyword
1 + 2 or keyword 3 + 4 in the filename. |
| > |
Search |
Keyword1 Keyword2 OR Keyword3 Keyword4
NOT Keyword5 |
| |
Boolean interpretation |
(Keyword1 AND Keyword2) OR ((Keyword3 AND
Keyword4) NAND Keyword5) |
| |
Explanation |
All files with keyword 1 + 2 or keyword
3 + 4 but any files matching 3 + 4 must not contain keyword
5 |
| > |
Search |
Keyword1 Keyword2 NOT Keyword5 OR Keyword3
Keyword4 NOT Keyword5 |
| |
Boolean interpretation |
((Keyword1 AND Keyword2) NAND Keyword5)
OR ((Keyword3 AND Keyword4) NAND Keyword5) |
| |
Explanation |
Similar to the example above with the only
difference that keyword 5 must neither appear with 1 +
2 nor with 3 + 4. |
| > |
Search |
(Keyword1 Keyword2 OR Keyword3 Keyword4)
NOT Keyword5 |
| |
Boolean interpretation |
((Keyword1 AND Keyword2) OR (Keyword3 Keyword4))
NAND Keyword5 |
| |
Explanation |
Same search as the one above but more elegant
through the use of ( ) to apply the NOT keyword5
to the entire OR expression |
| > |
Search |
(Keyword1 "OR" Keyword2) NOT
Keyword3 |
| |
Boolean interpretation |
(Keyword1 AND or AND Keyword2) NAND Keyword3 |
| |
Explanation |
By using " " to include the term, the OR operator
is no longer counted as such but as a regular expression.
This search translates to hits which must contain keyword1
and keyword2 and also the word "or" but must
not contain keyword3. |
Interpreting the Results
o Availability (Sources)
The availability is the number of sources found on the servers
for a download. This is not the total number of sources in
the entire net but serves as an indication how well spread
the file is. If there are different matching hits for a search
the file with highest availability should be chosen. Also
see Color coding of Search Results.
A value in ( ) behind the availability are sources which can
be added directly to the download without eMule having to
search for them again.
o Color coding of Search Results
| > |
Black, dark blue, light blue
Indicates the number of sources found for a specific
file. Black = 1 - 3 sources, dark blue = 4 - 9 sources,
light blue = 10+ sources |
| > |
red
Files already in the download list are shown in red |
| > |
Green
Hits shown in green are already downloaded and completed. |
o Searching within the results
Pressing CTRL + f shows a search dialog which can search for
keywords (File name), ID, size, type and availability. The
function key F3 jumps to the next found item with the same
search keyword while SHIFT + F3 jumps to the previously found.
o Multiple names found for one file
Files are identified by their hash values and not filenames.
A search may yield many different file names for the same
file. This is shown by an Explorer like + before the search
result. If a result has vastly different filenames, this may
be a fake.
Applies to version: .42a +
