This is an intelligent search engine for all the webpages and databases built into Norecopa's website:

• 3R Guide: Information on databases, guidelines, information centres, email lists and journals of relevance to laboratory animal science and the 3Rs. Short cut: Guidelines for animal research
• NORINA: Information on over 3,500 alternatives or supplements to animal use in education and training
• TextBase: Information on over 1,600 textbooks within laboratory animal science and related subjects
• Classic AVs: A subset of NORINA containing products using older technology
• NAL: bibliographic records relevant to the 3Rs from the database of the National Agricultural Library, USA
• European Commission Inventory of 3Rs Knowledge Sources: a dataset of over 800 resources

The search engine takes into consideration:

• the words which have been entered by the user
• an index of all the words in the databases
• a list of synonyms constructed by Norecopa specifically for these databases
• an "auto-complete" function which suggests search terms based on the search engine's own dictionary
• algorithms which prioritise or suppress words depending on their relevance
• Boolean operators, which the user can edit
• "fuzzy logic" (words resembling those entered by the user)

The user can limit a search to one or more of the databases and/or the webpages, and can turn on one or more filters to make the hit list as relevant as possible. 

Full details of the search engine's capabilities are available here.

The development of Norecopa's search engine and website has been sponsored by:

• Nordic Society against Painful Animal Experiments
• Novo Nordisk
• The Dag S. Stiansen Foundation

Norecopa is very grateful for this support. The development of the databases has been financed by many sponsors since 1991 when this work was started at the Norwegian School of Veterinary Science (the School and its sponsors).
