WebSphere Portal provides two search collections and a search scope. A search collection contains a number of content sources that the portal search service indexes. A search scope allows you to partition or organize your search collections. As a result your site visitors can limit their search to specific areas. Defined scopes are visible to visitors from the search dialog.
The search collections that are immediately available are Default Search Collection and JCRCollection1. A schedule for crawling and indexing is defined for each collection. You might want to review the schedule and make sure that the schedule time is appropriate for your site. For performance, do not run the crawler during peak times.
In addition to the scheduled time, you can also start the crawler manually. If you publish a large set of content, you might want to manually start the crawler to index the new content sooner.
