Categories

Categories enable you to group documents that share common characteristics. Users can then explore only the documents that meet the criteria for being members of that group.

If you associate documents with categories, and your applications support this capability, users can narrow results by exploring only the documents that belong to specific categories.

When you configure a rule-based category, you specify rules to associate documents with the category. You can group documents that share a URI pattern. You can also group documents that contain specific content (for example, documents that contain or exclude specific words and phrases).

By analyzing document clusters, the system can extract proposed metadata terms from subsets (clusters) of documents in the index. When you configure a category based on document cluster analysis, you select the cluster proposal that contains the words that you want to use for classifying documents.

If you change a category after documents are crawled and indexed, search quality is degraded until the documents are crawled and indexed again. If the collection is configured to use the document cache, you can rebuild the index without recrawling documents.
