One of the features in CA Service Desk Manager (CA SDM) is the auto-suggest feature (also known as search-as-you-type).
This feature allows you to perform dynamic, real-time matching using Search-As-You-Type to locate items quickly. As you type your term, the search field dynamically displays one or more matching results. You can use Search-As-You-Type on any lookup or drop-down list.
It might be desirable to adjust the number of records returned by the auto suggest feature.
