Welcome to the CLADDIER Discovery Service
About This Service
The CLADDIER Discovery Service is a pilot search engine, deployed by the CLADDIER project, to demonstrate search across documents and datasets from multiple sources, focusing on the environmental sciences.
This is an alpha release, and we'd really appreciate your feedback on any aspect of this service - please email your comments to the CLADDIER project team, starting the subject line with "discovery service feedback:".
What Can I Search For?
You can use this service to search for both datasets and documents.
The circle icon ... 
... indicates that the result is a dataset. The rectangular icon ... 
... indicates that the result is a document.
Where Does the Information Come From?
The results shown here come from three separate sources:
- CCLRC - CCLRC ePublication Archive.
- SOTON - e-Prints Soton, the University of Southampton Research Repository.
- BADC - British Atmospheric Data Centre.
How Does the Searching Work?
A query entered in the search box above is matched against all text in the metadata records held, including title, description, creators, date etc. The query is only matched against the metadata records, and not against the content of the documents or datasets.
Results are returned in relevance order. For each result, the title and a brief description is displayed, with links to information held at the source repository where available. Clicking on the 'More' link expands the result to display the full metadata record.
What's Our Goal?
The CLADDIER project is exploring new and automated ways of linking and discovering data and associated publications, and this Discovery Service is a first step towards that goal. It incorporates the University of Southampton and CCLRC Research Publication Repositories as exemplars of Institutional Repositories in the UK. The British Atmospheric Data Centre (BADC), likewise, is an exemplar of a discipline based data archive. The CLADDIER Discovery Service harvests metadata records from these repositories via the OAI-PMH protocol, indexes them, and makes them available via this search interface.
Help With Searching
Matching Terms
Search for single terms by simply entering the terms directly, e.g.:
surfactant
... this will match any record containing the term "surfactant".
You can also search for multiple terms simultaneously, e.g.:
ion surfactant
... this will match any record containing either "ion" or "surfactant", although records that match them both will be ranked higher.
Matching Phrases
You can match a phrase be enclosing the phrase in double quotes, e.g.:
"ion cloud"
.... this will match any record containing the text "ion cloud".
Wildcard Searches
You can use the wildcard characters "*" and "?" to perform wildcard searches. The "?" symbol is used for a single character wildcard search, and the "*" symbol is used for a multiple character wildcard search. E.g.:
gr?y
... will match records containing the text "grey" or "gray". E.g.:
surfac*
... will match records containing the text "surface" or "surfactant" or any word beginning with the characters "surfac".
Boolean Operators
You can use the boolean operators "AND", "OR" and "NOT" to construct more complicated queries. E.g.:
"fluoride ion" AND conductivity
E.g.:
fluoride NOT conduct*
