Oracle ATG Web Commerce Search is organized by projects, as discussed in the ATG Search Administration Guide. There are two main types of relationships between projects:
Independent projects have separate groupings of content for indexing. Two or more independent projects can index the same content or different content, but the indexes are totally separate and independent. A project’s content sets are grouped and identified for querying by one or more content labels.
Linked projects have identical content labels, but they differ by target type, which specifies the instance of the index that queries are directed to. In a set of linked projects, there is a main project whose target type is Production. Other projects are created as links to this project, and have different target types, such as Staging or Testing.
Each search project produces an index that comprises one or more logical partitions. The index has a separate logical partition for each content set in the project.
