Syntax

Smartsite SXML	Copy Code
string this.fieldname()

Parameters

This Viper method does not expose any parameters.

Return Value

Data Type	Description
String	The name of the field.

Used in

Macro	Description
FacetedSearchQueryBuilder	Builds an SQL query for Faceted Search.

Remarks

Returns the fieldname for which an additional search query is being assembled (to apply specific weights on physical fields). When used within an CONTAINSTABLE expression to indicate which columns must be used, you should specify an appropriate default:

this.fieldname(default="(QueryData,CTSpecificBinary1)")

Example

Faceted Search Query Xml - SearchBase Query Element Example (Fulltext)

The Faceted Search Query Builder macro (se:facetedsearchquerybuilder) contains a lot of local instance vipers. Usually, local instance vipers are used within the macro itself, e.g. formatting, but in this case the local instance vipers should only be used within a query xml definition.

This example shows a searchbase query element from a query xml definition in which some of the available local instance vipers are used. The example here is only applicable for a fulltext indexing scenario.
