propertyDescription	None

Attributes

Attribute	Description
inInvertedIndex	Public. Optional. Indicates whether the property value should be stored in the inverted index. This lets end users perform full-text queries over the values of this property. The default is "false".
isColumn	Public. Optional. Indicates whether the property should also be stored in the Windows search database as a column, so that independent software vendors (ISVs) can create predicate-based queries (for example, "Select * Where "System.Title"='qqq'"). If the schema creator wants to enable end users (or developers) to create predicate based queries on the properties, then this needs to be set to "true". The default is "false".
isColumnSparse	Public. Optional. The default is "true". If the property is multi-valued, this attribute is always "true".
columnIndexType	Public. Optional. To optimize sorting and grouping, the Windows search engine can create secondary indexes for properties that have isColumn="true". This attribute is only useful when inInvertedIndex is "true" in Windows Vista or when isColumn is "true" in Windows 7. If the property tends to be sorted frequently by users, this attribute should be specified. The default value in Windows Vista is "NotIndexed". The default value in Windows 7 is "OnDemand". The following values are valid. NotIndexed OnDisk OnDiskAll (Windows 7 and later only) OnDiskVector (Windows 7 and later only) OnDemand (Windows 7 and later only)
maxSize	Public. Optional. The max size allowed for a certain property that is stored in the Windows search database. The default is "128" (bytes).
mnemonics	Windows 7 and later. Public. Optional. A list of mnemonic values that can be used to refer to the property in search queries. The list is delimited with the '\|' character.
