CuramTerms are the part of the CuramQuery structure that represents search criteria.
There are three types of Terms: StandardTerm, a DateTerm, or a DateRange term. The CuramTerm object contains one of each of these types of these types, and has termType attribute specifying which of the term subtypes should be used. Only of one of the aggregated term subtypes is valid for each CuramTerm object.
For all term types, the 'field' attribute specifies the name of the Field in the Search Service to be searched (see Field and name). The 'value' attribute is the search criterion to be used - the meaning of this varies for the different types of terms and is described below.
