Indexing Properties in TREX as Strings

By default, TREX indexes properties of type String as Text properties. However, you can also specify that TREX is to index these properties as Strings.

However, you cannot perform a linguistic search for String properties.

   Parameter	Description
   Namespace Alias	Must be identical to the namespace of the first property
   Property ID	Property ID of the first property with the suffix _asString Example: Property ID of the first property: contenttype Property ID of the second property: contenttype_asString
   Additional Metadata	Add the entry IndexAsString.
