Categories store static facet values. These values display in the Refinements panel of the search results as well as in hit content. Static facet allow users to narrow their search results by focusing on a certain aspect of the results, such as a particular country or product line.
In the categories field, category values are stored in a tree. The root of the tree is called Top.
For example, for a given document, the categories field could contain the following categories:
You can use categories for navigation over static categories. To enable this navigation, Exalead CloudView stores the retrievable part of the category in RAM.
What is a Search Logic?
Search logics enable you to define:
• Which index fields or category facets to use for queries, using prefix handlers.
• What types of semantic interpretation to perform on queries, using semantic expansion modules.
• Which index fields or facets to return in the search results, using hit meta and facets.
You can create multiple search logics, which enables you to provide querying options and hit content specific for the destination search application.
Modifying the Index Schema and Search Logics
The simplest way to modify both the index schema and the search logic is to create classes and properties in the data model. For more information, see Using Properties to Configure Document Metas.
For advanced configurations, you can directly modify the analysis pipeline and search logic. See the following:
