Apache Solr

Cadmus provides an advanced query interface through Apache Solr that can be used to repurpose and disseminate content from Cadmus on other websites.

For EUI Academic Units

Content (metadata) from Cadmus automatically populates EUI departmental web pages and EUI project pages. When a new publication or dataset is submitted to Cadmus information will be also displayed on pages that are querying the Solr interface.

For everyone

Anyone can query the Cadmus SOLR interface. The Library Open Science team suggests SOLR XML output with the type of query that you can see below.

Example of query to obtain the "ECO Articles" collection: 

http://cadmus.eui.eu/search/select/q=search.resourcetype:3&fl=search.resourceid&fq=dc.title:ECO&fq=dc.title:Articles  

The query above return the following result:

<?xml version="1.0" encoding="UTF-8"?>
<response>
<lst name="responseHeader">
<int name="status">0</int>
<int name="QTime">3</int>
<lst name="params">
<str name="fl">search.resourceid</str>
<str name="q">search.resourcetype:3</str>
<arr name="fq">
<str>dc.title:ECO</str>
<str>dc.title:Articles</str>
</arr>
</lst>
</lst>
<result name="response" numFound="1" start="0">
<doc>
<int name="search.resourceid">16</int>
</doc>
</result>
</response>

From the response, the <int name="search.resourceid">16</int> give us the collection id.

We then launch the following query:

http://cadmus.eui.eu/search/select/q=*:*&fq=location.coll:16&fq=dc.date.issued_dt:[2015-01-01T00:00:00Z TO 2016-12-31T23:59:59Z]&fl=title,author,dc.indentifier.citation,dc.relation.ispartofseries,abstract,identifier,dc.identifier.uri,handle,dc.date.issued_dt&sort=dc.date.issued_dt+desc&start=0&rows=10

The query above will return the first 10 items from the collection "16", between 2015-01-01 and 2016-12-31, sorted by date issued descendent. For the following 10 items we have to modify the parameter start "&start=10"

Here a brief explanation of the query parameters used above:

• q=*.*   // query parameter. It’s all the items
• fq=location.coll:16  // a filter to obtain only items from the collection id 16
• fq=dc.date.issued_dt:[2015-01-01T00:00:00Z TO 2016-12-31T23:59:59Z] //a filter query to obtain only the items between the dates.
• fl=title,author,dc.indentifier.citation,dc.relation.ispartofseries,abstract,identifier,dc.date.issued_dt // enumerated list of metadata to return at the resultset.

To see all possible values, you can launch a query without this param. It returns all default values.

"Handle" is mandatory to obtain the files and thumbnailssort=dc.date.issued_dt+desc : Sorting configuration. Date issued descendentrows=10 : Number of rows to return. Used with the "start" param can make queries lighter.start=0 : Starting element.

The results can have a lot of elements that can be obtained repeating the same query.
