Type in the word(s) you are looking for.
Things to remember:
- The words are matched from the start:
Naturwissenschaft
will be found when looking forNatur
but NOT forwissenschaft
. Note: you can match words from anywhere in the word using the special character*
, see Advanced search. - All the words you type in will be present in each of the search results. For more refined results, see the section “Advanced search”.
- The search is case insensitive.
The filters allow you to refine the results: by language, subweb, or type of content, document or webpage (“Content”). The results can also be ordered either by relevance or date.
If you want to restrict the search to full words, tick the corresponding checkbox.
Query | Full words search | Is a match | Is not a match |
---|---|---|---|
Natur | No | Naturwissenschaft | |
wissenschaft | No | Naturwissenschaft | |
Natur | Yes | Naturwissenschaft |
Multiple words
When searching multiple words, the results will contain all the words of the query.
Example: Schmidt Jensen
will retrieve all content containing both Schmidt
and Jensen
, anywhere on the page. The words will not necessarily be close to one another.
To find an exact set of words (phrase), add double quotes, e.g. ”transparent and comprehensive"
.
Query | Is a match | Is not a match |
---|---|---|
Meier Müller | Meier and Müller worked on | Meier worked on |
”transparent and comprehensive" | The research is transparent and comprehensive |
The research is transparent, comprehensive and robust |
Note: do not use AND
and OR
keywords in this mode. If they are necessary, use the advanced research mode.
Advanced search
When selecting the option “Extended search parameters” from the “Search mode” field, you can define the request more precisely.
In this mode, the default is that at least one word of the request must appear in the results.
Example: Meier Müller
will retrieve all content containing either Meier
, Müller
, or both.
Query | Is a match | Is not a match |
---|---|---|
Meier Müller | Meier and Müller worked on | |
Meier Müller | Meier worked on |
Keyword OR
The default behavior of this mode is to retrieve results with any of the words, making the keyword OR in practice optional.
The keyword OR is to be used when any of the 2 words must be present.
Example: Meier OR Müller
is equivalent to Meier Müller
and will retrieve all content containing either Meier
, Müller
, or both.
Query | Is a match | Is not a match |
---|---|---|
Meier OR Müller | Meier and Müller worked on | |
Meier OR Müller | Meier worked on |
Keyword AND and special character +
To force several words to be in the results, separate them with the keyword AND (must be uppercase). In this case, both words will be in the results. Alternatively, it is possible to prepend the words with a + sign (no space): the next word is then required.
Example: Meier AND proton
gives the same results as +Meier +proton
: pages containing both words.
Query | Is a match | Is not a match |
---|---|---|
Meier AND Müller | Meier and Müller worked on | Meier worked on |
+Meier +Müller | Meier and Müller worked on | Meier worked on |
Keyword NOT and special character -
It is possible to retrieve results that do not contain certain words. If a word should not be in the results, add the word NOT
in front of it (must be uppercase). Alternatively prepend the word with a -
sign (no space).
Example: Meier NOT proton
gives the same results as Meier -proton
: pages containing the word Meier
and nowhere the word proton
.
Query | Is a match | Is not a match |
---|---|---|
Meier NOT proton | Meier worked on muon | Meier worked on proton |
Meier -proton | Meier worked on muon | Meier worked on proton |
Parentheses
For more complex queries, you can use parentheses.
Example: if you look for the words Schmidt
or Jensen
, but always associated with proton
, then use (Schmidt OR Jensen) AND proton
. Note that the query Schmidt OR (Jensen AND proton)
will give different results. We recommend to always use parentheses when performing more complex queries.
Query | Is a match | Is not a match |
---|---|---|
(Meier OR Müller) AND proton | Meier worked on proton | Meier worked on muon |
Meier OR (Müller AND proton) | Meier worked on muon Meier worked on proton Müller worked on proton |
Müller worked on muon |
Wildcard search: ? and *
If you need to add flexibility to a query, you can use the special characters ?
and *
.
?
will match any one character.
Example: Jörgen
, Jørgen
and Jorgen
will be found when querying J?rgen
, but Joergen
will not (oe
is two characters-long).
*
will match any number of characters. For example, *wissenschaft
will match Naturwissenschaft
, Umweltwissenschaft
, Ingenieurwissenschaft
, as well as wissenschaft
, whatever the number of characters replacing *
.
Note that the words are matched from the beginning in this mode as well. *
can be useful to query for parts of words that are not at the beginning of the word, such as the wissenschaft
example.
The special character can also be used inside a word: J*rgen
will match Jörgen
, Jorgen
and Joergen
, but Julsbergen
will also be a match.
Query | Is a match | Is not a match |
---|---|---|
J?rgen | Jorgen, Jörgen, Jørgen | Joergen, Jrgen |
J*rgen | Jörgen, Jorgen, Joergen, Julsbergen, Jrgen | |
*wissenschaft | Wissenschaft, Naturwissenschaft |
