Search Service Architecture

Search Service Architecture

The Search Service interacts with different components in the Informatica domain when it builds the search index and returns search results. The Search Service can build a search index based on content in a Model repository and a profiling warehouse.
The following diagram shows the Informatica domain components with which the Search Service interacts:
The diagram shows how the Search Service uses extractors to build the search index based on objects in a Model repository and a profiling warehouse. The diagram also shows how Informatica Analyst and Business Glossary Desktop submits search requests to the Search Service.
When you create the Search Service, you specify the associated Model Repository Service. The Search Service determines the associated Data Integration Service based on the Model Repository Service.
To enable search across multiple repositories, the Search Service builds a search index based on content in one Model repository and one profiling warehouse. To enable search on multiple Model repositories or multiple profiling warehouses, create multiple Search Services.
The Search Service extracts content, including business glossary terms, from the Model repository associated with the Model Repository Service. The Search Service extracts column profile results and domain discovery results from the profiling warehouse associated with the Data Integration Service. The Search Service also extracts permission information to ensure that the user who submits a search request has permission to view each object returned in the search results. The Search Service stores the permission information in a permission cache.
Users can perform a search in the Analyst tool or Business Glossary Desktop. When a user performs a search in the Analyst tool, the Analyst Service submits the request to the Search Service. When a user performs a search in Business Glossary Desktop, Business Glossary Desktop submits the request to the Search Service. The Search Service returns results from the search index based on permissions in the permission cache.
