The search bar is located in the icon bar.
To make the cursor jump to the search field, you can:
Click in the search field.
Press Ctrl + F.
At the right of the search text field, 2 buttons allow for selecting some settings:
Regular expressions
Whether or not the search query uses regular expressions.
Case sensitivity
Whether or not the search query is case sensitive.
In a normal search, the program searches your database for all occurrences of the words in your search string, once you entered it. Only entries containing all words will be considered matches. To search for sequences of words, enclose the sequences in double-quotes. For instance, the query progress "marine aquaculture" will match entries containing both the word "progress" and the phrase "marine aquaculture".
All entries that do not match are hidden, leaving for display the matching entries only.
To stop displaying the search results, just clear the search field, press Esc or click on the "Clear" (X
) button.
In order to search specific fields only and/or include logical operators in the search expression, a special syntax is available in which these can be specified. E.g. to search for entries whose an author contains miller, enter:
author = miller
Both the field specification and the search term support regular expressions. If the search term contains spaces, enclose it in quotes. Do not use spaces in the field specification! E.g. to search for entries about image processing, type:
title|keywords = "image processing"
You can use and
, or
, not
, and parentheses as intuitively expected:
(author = miller or title|keywords = "image processing") and not author = brown
The =
sign is actually a shorthand for contains
. Searching for an exact match is possible using matches
or ==
. Using !=
tests if the search term is not contained in the field (equivalent to not ... contains ...
). The selection of field types to search (required, optional, all) is always overruled by the field specification in the search expression. If a field is not given, all fields are searched. For example, video and year == 1932
will search for entries with any field containing video
and the field year
being exactly 1932
.
JabRef defines the following pseudo fields:
| | |
Pseudo field | Purpose | Example |
| Search in any field |
|
| Search among the keywords |
|
| Search for citation keys |
|
| Search for entries of a certain type |
|
Regular expressions (regex for short) define a language for specifying the text to be matched, for example when searching. JabRef uses regular expressions as defined in Java. For extensive information, please, look at the documentation and at the tutorial.
They can be used in the normal search mode and the advanced search mode
By default, regular expressions do not account for upper/lower casing. Hence, while the examples below are all in lower case, they match also upper- and mixed case strings.
If casing is important to your search, activate the case-sensitive button.
.
means any character
+
means one or more times
author != .+
\b
means word boundary
\B
means not a word boundary
keywords = \buv\b
matches uv but not lluvia (it does match uv-b however)
author = \bblack\b
matches black but neither blackwell nor blacker
author == black
does not match john black, but author = \bblack\b
does.
author = \bblack\B
matches blackwell and blacker, but not black.
?
means none or one copy of the preceding character.
{n,m}
means at least n, but not more than m copies of the preceding character.
[ ]
defines a character class
title =neighbou?r
matches neighbour and neighbor, and also neighbours and neighbors, and neighbouring and neighboring, etc.
title = neighbou?rs?\b
matches neighbour and neighbor, and also neighbours and neighbors, but neither neighbouring nor neighboring.
author = s[aá]nchez
matches sanchez and sánchez.
abstract = model{1,2}ing
matches modeling and modelling.
abstract = modell?ing
also matches modeling and modelling.
year == 200[5-9]|201[0-1]
specifies the range of years 2005-2011 (200[5-9]
specifies years 2005-2009;|
means "or"; 201[0-1]
specifies years 2010-2011).
If a special character (i.e. (
)
[
]
{
}
\
^
-
=
$
!
|
?
*
+
.
) is included in your search string, it has to be escaped with a backslash, such as \}
for }
.
It means that to search for a string including a backslash, two consecutive backslashes (\\
) have to be used: abstract = xori{\\c{c}}o
matches xoriço.
The character "
has a special meaning: it is used to group words into phrases for exact matches. So, if you search for a string that includes a double quotation, the double quotation character has to be replaced with the hexadecimal character 22 in ASCII table \x22
.
Hence, to search for {\"o}quist
as an author, you must input author = \{\\\x22o\}quist
, with regular expressions enabled (Note: the {
, _
and the }
are escaped with a backslash; see above).
Indeed, \"
does not work as an escape for "
. Hence, neither author = {\"o}quist
with regular expression disabled, nor author = \{\\\"O\}quist
with regular expression enabled, will find anything even if the name {\"o}quist
exists in the database.
