Add a property to the property cache

Open Computer Management
In the console tree, under the appropriate catalog, click Properties.
Where?
- Computer Management
- Services and Applications
- Indexing Service
- catalog
- Properties
In the details pane, in the Property Set column, click the property ID of the property you want to add to the cache.
On the Action menu, click Properties.
In the Properties dialog box, select the Cached check box.
In the Size box, for variable-size properties, set the size (in bytes) for the property. (You cannot change the size for a fixed-size property.)
If you want the property to be stored in the primary level of the cache, in the Storage list box, click Primary.

Important

Making changes to the property cache can have substantial impact on the performance of Indexing Service.

note Note

To open Computer Management, click Start, point to Settings, and then click Control Panel. Double-click Administrative Tools, and then double-click Computer Management.
The changes take effect the next time you start Indexing Service.
The Data Type list box automatically shows the appropriate data type for the property if the property is known to Indexing Service. If it is not known, VT_LPWSTR is displayed. You can choose another data type from the list.
Adding properties to the primary level of the cache can cause performance to slow.
The primary level is optimized for fixed-length properties. Avoid storing variable-length properties there because that will greatly increase the space required for the cache.
After you choose a storage level for a property and restart Indexing Service, you cannot change it.
You must rescan all indexed documents before the new properties are stored.
