CORDIS search interface is available at https://cordis.europa.eu/search/en
The search interface allows you to:
The filters menu available at the side of the search interface offers the most common filters for a general use.
You can also enter search terms in the search box available at the top of the search interface.
Searched terms will be searched separately, e.g. searching for sustainable agriculture will generate the query 'sustainable' AND 'agriculture'.
sustainable agriculture
'sustainable' AND 'agriculture'
If you want to search for an exact phrase you have to use single quotes: 'sustainable agriculture'.
'sustainable agriculture'
Double quotes are also valid as they will be normalized to single quotes by the system: "sustainable agriculture".
"sustainable agriculture"
When searching for terms, wildcards can be useful to find different variations of a word.
A wildcard is a character that substitutes for another character or string of characters.
The wildcards that you can use are the asterisk (*) and the question mark (?): * matches zero or more non-space characters ? matches exactly one non-space character
For example, searching for educat* will match any word starting with educat, such as educate, educated, education, educational or educator.
educat*
Searching for organi?ation matches organization or organisation.
organi?ation
Wildcards can sometimes give you a large number of irrelevant results. In this case, you may want to skip the wildcards and enter the different search terms in full.
You can combine search filters with search terms entered in the search box. Your search terms will act as another filter added to your query.
For example, searching for projects in the field of embryonic stem cell research, you launch a search based on the following filters:
Collection: Projects Field of Science: stem cells
You can further filter your search results by entering the embryonic keyword in the search box.
embryonic
Selecting 'Edit query' next to the search box will show the query generated for your search, in edit mode.
In this mode you can learn the data structure and the query syntax, and you can enter your own search queries based on a combination of the following elements:
See above.
With logical operators you can combine your search terms, or exclude a specific search term.
There are three operators that you can use: AND, OR, NOT, plus the () parentheses that are used to group terms together.
AND allows you to narrow your search to only retrieve results that include all items in a list chemical AND electrical AND mechanical
chemical AND electrical AND mechanical
OR allows you to broaden your search to retrieve results that include one or more items in a list science OR scientist OR scientific Many people incorrectly think the OR operator is an either/or operator (exclusive or), when in fact it is an and/or operator (inclusive or).
science OR scientist OR scientific
NOT allows you to exclude terms you don't want to appear in your search results. wood NOT plastic
wood NOT plastic
If different operators are used in the same query, the search is processed according to this order of precedence: the NOT operator has the highest precedence, followed by the AND operator, followed by the OR operator.
() parentheses You can always control (override) the operator precedence by enclosing your terms and their operators in parentheses. The information within parentheses is interpreted first, and then information outside the parentheses is interpreted next. Within each set of parentheses, operator precedence applies.
For example, sustainable OR ecological AND farming finds all records in which both ecological and farming are present, as well as all records in which the word sustainable is present.
sustainable OR ecological AND farming
(sustainable OR ecological) AND farming finds all records in which the word farming is present together with either sustainable or ecological.
(sustainable OR ecological) AND farming
If there are nested parentheses (i.e. parentheses within parentheses), the search engine processes the most enclosed parenthetical expression first, then the next, and so on until the entire query has been interpreted. For example, ((rain OR shower) AND storm) OR rainstorm
((rain OR shower) AND storm) OR rainstorm
XPaths are used for selecting nodes from an XML document. The queries that are generated when you search with the filters menu are based on XPaths.
For example, selecting the following filter values:
Collection: Results Packs, Results in Brief, News, interviews Domain of Application: Climate Change and Environment Language: English
will generate the query: (/article/relations/categories/collection/code='resultsPack','brief','news','interview') AND language='en' AND applicationDomain/code='env'
(/article/relations/categories/collection/code='resultsPack','brief','news','interview') AND language='en' AND applicationDomain/code='env'
From the path to a specific node in the XML of a record, you can deduce the corresponding XPath and use it in your own queries.
You can use specific XPaths that are not available in the search filters menu, e.g.
Searching for closed projects: /project/status=CLOSED
/project/status=CLOSED
Searching for projects with a duration of 36 months: /project/duration=36
/project/duration=36
Searching for projects having a partner organization: /project/relations/associations/partner/organization/id='*'
/project/relations/associations/partner/organization/id='*'
Searching for projects having a participant organization with a "terminated" attribute: /project/relations/associations/participant/organization/_ATTR_terminated='true'
/project/relations/associations/participant/organization/_ATTR_terminated='true'
Searching for projects having a third party and/or an international partner organization: /project/relations/associations/thirdParty/organization/id='*' OR /project/relations/associations/internationalPartner/organization/id='*'
/project/relations/associations/thirdParty/organization/id='*' OR /project/relations/associations/internationalPartner/organization/id='*'
The XPaths used by the different filters in the search interface are provided in the section: Quick guides - XPaths used in search filters.
cancer AND treatment
cancer AND treatment AND therapy
doctorate OR degree
viruses NOT bacteria
viruses AND NOT (bacteria OR fungi OR parasites)
'circular economy'
"circular economy"
Hof*man*
organi?ation*
pollution OR environment AND water
(pollution OR environment) AND water
water AND ((wheel OR mill) AND NOT 'generators and turbines')
water AND (wheel OR mill) AND NOT 'generators and turbines'
