Search Descriptor Schema

https://ns.adobe.com/xdm/common/descriptors/searchdescriptor

Describes how XDM properties are to be handled for search, including the application of analyzers and operation in queries. The search:indexed descriptor is set to true to indicate that a property should be indexed, as specified by the values of the other search descriptor properties. When search:index is false (including by default), the other search descriptors will be ignored.

Descriptors

Descriptor Description Values Default
search:indexed Whether this property is to be indexed true, false false
search:store Whether values are stored in the index and, if so, are included in results by default notStored, stored, storedAndFetchByDefault notStored
search:filterable When this property can be used as a filter in queries true, false false
search:sort Whether and how sorting is applied to this property notSortable, sortedCaseSensitive, sortedCaseInsensitive notSortable
search:analyzers The set of analyzers applied to property values during indexing See Analyzers, below [ noAnalysis ]
search:defaultAnalyzer The analyzer output to be used when a query reference to this property is made without also specifying the analyzer See Analyzers, below
