This section describes the steps involved in creating a Search index.
More than one index can be built at the same time, if enough indexing engines are available (see the ATG Search Installation and Configuration Guide for architecture recommendations). The indexes must be for different Search projects. When indexing is complete, the resulting indexes can be automatically copied to Search environments.
Some customization data types can only be applied when you fully index content from scratch, and any changes to them require reindexing. These are known as “preindex customizations,” and include the following types:
Dictionaries
Term Weight Sets
Text Processing Option Sets
Note that the text processing option sets are not loaded themselves, but direct the indexing of other content.
Other customization data types can be applied after the content is indexed, and do not require that you reindex the content to apply changes, though you do need to update the index with the new customization data. The following types of customization data can be changed without reindexing your content:
Query Rules
Topic Sets
Facet Sets
Auxiliary Data
Merchandising Search Configurations
To build an index using the project’s default settings:
On the Projects tab, go to Projects > Your Project.
In the Indexing section of the page, click Build Index.
If you do not want the indexing process to pause after estimating the size of your index, uncheck the Indexing Plan Estimation checkbox.
Click OK. The window changes to the Status Monitor tab.
If you have selected to stop indexing after estimation, when the estimation is finished, click Continue Indexing.
To build an index using settings other than the project defaults:
On the Projects tab, go to Projects > Your Project > Indexing > Index Setup tab.
Full—Builds your entire index from scratch, using the content sets you select and the most up-to-date customization data, then deploys to the environment(s) you select.
Incremental—Only indexes new or modified content in an existing index. You select whether or not to apply post-indexing customization data.
Note: Incremental indexes involve comparing old to new content to determine changes, and can take longer to build than a full index. You need to do at least one full index before using incremental indexing.
Custom—Allows you to select from the following option sets:
Use a clean index partition, or update the existing index.
Deploy the new index, or do not deploy.
Load Post-Index Customizations Only—Updates the index by reapplying post-index customization data (such as topics) but makes no other changes. You can either apply all post-index customizations, or specify customizations to apply.
Deploy Only—Deploys your existing index to the selected environment(s) without making any changes.
Select content to Index. Only the Incremental and Custom (using existing index) indexing tasks allow you to specify which content sets are indexed. On the Index Setup tab, you can choose either All Content Sets or Select One or More Content Sets.
If you choose Select One or More Content Sets, a list of your content sets is displayed. Click the checkbox to select those content sets you want to index.
Select customizations. The indexing task you select may allow you to choose whether to apply all customizations, or only selected post-indexing customizations.
Select deployment environments. Some indexing options allow you to deploy the indexed content when indexing is concluded. Check the environments to which you want to deploy the index.
Click Build Index. The status monitor shows the progress of index creation.
Note: The Time Remaining estimate reflects only index creation. File deployment may take additional time.
Note: You can build indexes for separate projects in parallel; however, each project can only build a single index at one time.
