You can install and configure IBM® Content
Search Services for a single server configuration
or a multiple server configuration on Windows®, AIX®, Linux®, and Solaris
operating systems.
IBM FileNet® Content Engine preprocesses
documents and sends them to the IBM Content
Search Services index
server for indexing. Depending on the size and configuration of your
system, you might want to have multiple instances of IBM Content
Search Services installed on your system.
In a single server configuration, a single instance of IBM Content
Search Services performs both the indexing
and searching tasks for the Content Engine.
In a multiple server configuration, you assign different roles
to your
IBM Content
Search Services instances
to distribute the load for both indexing and searching tasks. You
can run multiple instances of
IBM Content
Search Services on the same computer for vertical scaling or you can run
them on different computers for horizontal scaling. Each instance
of
IBM Content
Search Services can be designated
to do only indexing tasks, searching tasks, or both. You designate
which tasks each
IBM Content
Search Services server does by assigning it a specific server mode:
- Index
- Content Engine sends only indexing tasks
to servers in this mode. You can have multiple, dedicated index servers
to distribute the indexing load for high volume scenarios. Multiple
index servers also allow failover capability for the Content Engine. If one indexing server
goes offline, the Content Engine automatically distributes the indexing load to the remaining indexing
servers.
- Search
- Content Engine sends only
searching tasks to servers in this mode. You can have multiple, dedicated
search servers to distribute the searching load when you have many
indexes to search. Multiple search servers also allow failover capability
for the Content Engine. If one
search server goes offline, the Content Engine automatically selects an alternate search server to perform
its tasks.
- IndexAndSearch
- Content Engine sends both
indexing and searching tasks to servers in this mode. The IndexAndSearch
server mode is typically used in a single server configuration.
Set up the site to contain the object store and the IBM Content
Search Services servers. All of the documents
and other objects are indexed in the same site as the object store.
