The following table describes the steps in the preparation phase.
Step | Description | Related information | |
---|---|---|---|
1 | Index request submission | An index request is generated for an object when Content Platform Engine or an application creates,
updates, or deletes an object that belongs to a CBR-enabled class.
The application might be the administration console or a custom application
that calls Content Engine API
methods. A batch of index requests can also be generated at one time as part of an index job. An index job is automatically created when you choose a CBR-enabled class or object to be indexed in the administration console. An index job is also created when you manually choose to reindex a selected index in an index area. |
For information about creating an index job using the administration console, see Creating an index job. |
2 | Index determination | Content Platform Engine determines the index area and the target index file to update for the index request. | For information about how Content Platform Engine determines the index for an object, see Resource statuses and object index entry assignment. |
3 | Index request batching | The Content Platform Engine subsystem dispatcher groups the index request with other index requests to form an index batch. The target full-text index is the same for all index requests in a batch. | For information about accessing the following properties in
the administration console, see Accessing subsystem configuration properties:
|
4 | Text extraction | A worker thread for the subsystem dispatcher converts any binary documents to text documents. An example of a binary document is a Microsoft Word document. The index request object might have zero or more content elements that are binary documents. | For information about accessing the following properties in
the administration console, see Accessing subsystem configuration properties:
For more information about text extraction, see Controlling text extraction. |
5 | Index server workload rebalancing | For load balancing purposes, the subsystem dispatcher checks
if a different index server must be assigned to the target full-text
index. To control the way that index servers are assigned to full-text indexes, you can create affinity groups to dedicate index servers to particular index areas. |
For information about creating affinity groups, see Creating an affinity group. For more information about rebalancing, see Index server workload rebalancing. |
6 | Index batch submission | A worker thread for the subsystem dispatcher submits the text document as part of an index batch to an index server. The phrase text document refers to the text that is indexed for a Content Platform Engine object. | For information about accessing the following properties in
the administration console, see Accessing subsystem configuration properties:
