How to search
Choose your search method
Flexible matching is the default behavior and will ignore word endings using stemming.
Exact matching will match exact words only. In this mode it is advised to use wildcards to match word-variations.
Clustering and operators
Use parentheses and boolean operators to cluster different search combinations.
AND is the default if you do not type anything between multiple search terms. The search operators
OR must be in all caps.
(waste OR pollution) AND (denmark OR sweden)
You can limit your search result to certain document types by clicking "Journal article", "Book" or "Journal" in the left hand menu.

Search for a phrase by enclosing words in quotation marks -
"neural circuit". This will find results where the words are next to each other.
When using Flexible matching stemming will still be applied, i.e.
"neural circuit" will also return results for "neural circuits".
You can specify search terms to be within a certain number of words apart. To do a proximity search use the tilde
~ symbol at the end of a phrase. To search for carbon and spectra to be within 3 words of each other in a record, specify the search like this:
When using Flexible matching words are compared by their "stem". Searching for
waters will find results containing
The algorithm used to find the stem is for the English language so it will not work correctly in other languages.
Wildcards and truncation
Wildcards can be used with both flexible matching and exact matching but NOT inside phrase searches.
A question mark
? matches a single character. The query
organi?ation will find both
organisation, but not
* matches zero or more characters. The query
organ* will find
Wildcards can be used in the middle of a word. The query
org*ally will find
Year range searches
