The MDEX Engine URL query parameters listed in this topic are available to control the use of EQL requests.
Nrs- TheNrsparameter specifies an EQL request that restricts the results of a navigation query. This parameter links to the JavaENEQuery.setNavRecordStructureExpr()method and the .NETENEQuery.NavRecordStructureExprproperty. TheNrsparameter has a dependency on theNparameter, because a navigation query is being performed.Ars- TheArsparameter specifies an EQL request that restricts the results of an aggregated record query. This parameter links to the JavaENEQuery.setAggrERecStructureExpr()method and the .NETENEQuery.AggrERecStructureExprproperty. TheArsparameter has a dependency on theAparameter, because an aggregated record query is being performed.Drs- TheDrsparameter 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.DimSearchNavRecordStructureExprproperty. TheDrsparameter has a dependency on theDparameter.
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.
