VerityCollection
is associated with only one IndexArea, and the full text information is stored in a file system directory identified by the VerityIndexArea.RootDirectoryPath property
. For each
object in the Content Engine database, there is a corresponding collection maintained by the Verity software that actually holds the full text index data. The name of this collection is identified in the
property.
objects are automatically created by the server when needed, and do not need to be created by a client application. When full text indexing is available, and the first instance of a class is created or modified, the server looks for an existing
associated with the appropriate base class, and will use this
. If a
is not found, a new
is created, along with the corresponding collection maintained by the Verity software.
An application can set the
property to "closed" if a problem occurs with writing data to a particular
, or to "unavailable" if the collection is expected to be made available again eventually.
The
property is set to "full" by the server when the number of rows in the collection is greater than
(no new data will be written to the collection). Whenever a collection is needed for writing full text information, the collection is selected from the list of eligible "open" collections. If no open collection exists, then a collection with a status of "standby" is selected, and that collection’s status is changed to "open".
New indexing information is written only to collections having a status of "open". However, all collections, regardless of their status, are searched when queries are performed. To prevent a collection from being searched, the associated
object must be deleted.
The following tables list the members exposed by IVerityCollection.
Public Properties
Name | Description | |
---|---|---|
![]() | BaseClassIds | The IDs of the base classes associated with the instance. There will only be one ID value in this property for release 4.0 (or later) installations. For installations upgraded from a release prior to 4.0, there may be both and class ID values in this property, since these releases stored indexing information for both the and objects in the same Verity collection. |
![]() | CollectionName | The name assigned to the Verity collection. |
![]() | Id | A representation of the Globally Unique Identifier (GUID), a unique 128-bit number, that is assigned to this Content Engine object when the object is created. When converted to a string, the Id property is typically depicted as 32 hexadecimal characters enclosed by brackets in the following format: {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}. For example, {3F2504E0-4F89-11D3-9A0C-0305E82C3301}. For For a given property representation, the Id property has the following characteristics:
For a newly created document object, you can override the Id property of its associated |
![]() | OriginalOrdinal | The ordinal number of the Verity collection if this collection was created prior to the Content Engine 4.0 release. For objects indexed in this collection, an arithmetic function is performed on the object's GUID to map it to an ordinal number, indicating this ordinal number (the collection in which the object resides). |
![]() | ResourceStatus | Contains a object, which specifies the availability status of a storage or index area. The status value can be any one of the following:
Note: When the The Content Engine supports the following automatic transitions between status values:
An area's status can also be changed manually as allowed by the following rules:
