Search tips

You can make more precise and/or complex search queries by using DDFs prefixes and search operators – get tips on how to make your searches better below.

A combination of search terms, e.g. Water Technical University will return records that have all words present somewhere in their data (metadata).

Use “” quotations for a precise search – for instance if you want to look up a specific title.

Use = as an OR search making it possible to combine AND / OR queries, e.g. Water=Aqua Denmark=Danmark

Use ? for truncation Water=Aqua D?nmark This search would return the same result as above.

Use prefixes to search in specific bibliographic elements e.g.: TI:university will return records that has the word “university” in the title. More Search codes
