Info

Note: The CLAIMS Direct SOLR Solr index does not store all text. This means that although the entire index is searchable, only certain fields are available for inclusion in a result set. For a list of retrievable fields, see the Quick Guide to Stored Solr Fields. You can also consult the schema where @stored="true", or use the the schema method of the search service to inspect field attributes.

The CLAIMS Direct Index is created and maintained using Apache SOLR Solr (http://lucene.apache.org/solr/) and hence, based on a schema definition, all functionality exposed by SOLR Solr is available through this search web service, including the entire Apache Lucene query language, result set sorting, facet searching, grouping etc. SOLR Solr is an extremely versatile and robust search platform and it is advised to fully familiarize yourself with SOLR Solr and Lucene (http://lucene.apache.org/java/docs/index.html), upon which SOLR Solr is built, before attempting to use this service.

...

The schema method returns the SOLR Solr schema field definitions. This service, like the search service below, is built directly on top of the SOLR Solr Schema API and therefore exposes all read-only functionality available.

/search/query

This service is built directly on top of the SOLR Solr REST services and therefore, unless otherwise noted, accepts all parameters that SOLR Solr REST services accept. For a comprehensive treatment, please see SOLR Solr Query Parameters. Bulk downloads are not supported through shared services. Search is limited to 30K documents per batch because deep paging can place undue stress on the system.

Method(s)GET | POST
 
Path/search/query
  

Common Query Parameters:

ParameterValueDescription
@qString: ex. solarAny syntactically correct search string
@qtString: ex. attachmentsOptional parameter to specify attachment search
@flString: ex. ucid,ttlComma-separated list of fields to return. Default
is all stored fields. (Note: These fields
fields returned without an "fl" parameter include ucid, ttl_en, ab_en, and score. Any field explicitly used must have the attribute stored="true"
)
.
@rowsInteger: ex. 25Positive value indicating maximum number of documents to return. Default value is 10.
@startInteger: ex. 0

0-based offset into result set. This parameter as well as the @rows parameter above can be used for paging. Default value is 0.

Maximum @start value is 30000. Values above 30000 will be reset to zero. This limit is in place to prevent

SOLR

Solr "deep paging" which causes serious memory swapping on the

SOLR

Solr servers.

@attachments (v2.5, JSON only)Boolean: ex. 1|0Return attachment list per ucid when available
@family.simple (v2.5, JSON only)Boolean: ex. 1|0Return the simple family per ucid when available
@family.extended (v2.5, JSON only)Boolean: ex. 1|0Return the extended family per ucid when available
@ls (v3.4, JSON only)Boolean: ex. 1|0Return all legal status information per ucid when available
@ls.country (v3.4 JSON only)String: ex. USReturn legal status information per ucid published by a particular country. Currently supported: US (PAIR) and EP (Inpadoc)
@citations.backward (v3.7 JSON only)Boolean ex. 1|0Return all backward citations per ucid when available
@citations.forward (v3.7 JSON only)Boolean ex. 1|0Return all forward citations per ucid when available

Info

Note: As of CDWS v2.4, a special HTTP header HTTPS header Accept type of text/x-solr returns the raw SOLR Solr response. There is no paging block, nor response wrapper.
