The MDEX Engine URL query parameters listed in this topic are available to control the use of EQL requests.
Nrs
- TheNrs
parameter specifies an EQL request that restricts the results of a navigation query. This parameter links to the JavaENEQuery.setNavRecordStructureExpr()
method and the .NETENEQuery.NavRecordStructureExpr
property. TheNrs
parameter has a dependency on theN
parameter, because a navigation query is being performed.Ars
- TheArs
parameter specifies an EQL request that restricts the results of an aggregated record query. This parameter links to the JavaENEQuery.setAggrERecStructureExpr()
method and the .NETENEQuery.AggrERecStructureExpr
property. TheArs
parameter has a dependency on theA
parameter, because an aggregated record query is being performed.Drs
- TheDrs
parameter specifies an EQL request that restricts the set of records considered for a dimension search. Only dimension values represented on at least one record satisfying the filter are returned as search results. This parameter links to the JavaENEQuery.setDimSearchNavRecordStructureExpr()
method and the .NETENEQuery.DimSearchNavRecordStructureExpr
property. TheDrs
parameter has a dependency on theD
parameter.
These parameters (including the EQL expression) must be URL-encoded. For example, this query:
collection()/record[Recordtype = "author"]
should be issued in this URL-encoded format:
collection%28%29/record%5BRecordtype%20%3D%20%22author%22%5D
However, the examples in this chapter are not URL-encoded, in order to make them easier to understand.
