Search

Keyword search (Documents) is selected by default. You can also choose other options,

Researchers helps to identify the right author in case there are multiple authors with the same name (the search can be specified by adding the research domain and affiliated organization); 
Cited References lets you search for works which have cited some other specific works; 
Structure Search is for searching the chemical indexes and requires creating an account and logging in.  

At the bottom of the search page, there is also Advanced Search, where you can enter search words with field codes and create more complex searches.

Basic Search allows searching for literature on some certain topic (Topic – search will cover the title, abstract and keywords given by the author). The search can be limited to the words found only in the title of the article, but it can also be made by the authors, the publication name, addresses (university, location) and other characteristics.

Building up a query

Search words can be connected by logical operators AND, OR and NOT, the proximity operator is NEAR. The search water NEAR/5 consumption will find entries where these words can be found up to five words apart from each other. 

In order to search an exact phrase, the phrase should be put between quotation marks. If you submit your query without quotation marks, the search engine will automatically insert the operator AND between the words of the phrase.

Wildcards can be used either in the beginning, in the middle or in the end of the word. The wildcards are:

– asterisk (*) – a substitute for any number of letters
– dollar sign ($) – a substitute for 0 to 1 letter
– question mark (?) – a substitute for only one letter.

NB! These databases are not provided with a subject thesaurus for choosing words for describing the content. Thus, it is very important to include as many key words, expressing one and the same concept, as possible in the search.

Searching in Document search by author select the author field and enter the last name and initial (s) to automatically search for all first names beginning with that letter. Do not write the first name.

Indexes are also linked when searching by Publication Name and Organization.

In all the searches you can specify the time period (starting from 1980) or a year, or search only for more recent articles which have been added within a preceding week, two weeks or a month.
