Final answer:
Customer Service Representatives (CSRs) use enabled Customer Service Datasources for searching terms, and each datasource must specify a Search Activity to aid in querying process. Relevant concepts likely involve database management and search algorithms.
Step-by-step explanation:
When Customer Service Representatives (CSRs) search on a term, each Customer Service Datasource that is enabled for search is queried. It is a required configuration for these datasources to specify a Search Activity. This process ensures that when a term is entered into a search, all relevant data sources are scanned, and their respective search activities help in retrieving the pertinent information from each source. Although not explicitly mentioned in the question, this architecture likely involves an understanding of database management, search algorithms, and possibly user interface design principles.
