The basic catalog lookup is working. The number of items returned by a given search criterion might be large. For example, if the user typed in the letter A or the word The, a large number of songs would be matched. The match processing could put restrictions on searches for common words. However, a large number of matches still would be possible. The display widget (e.g., a drop-down list or a web page) could have difficulty showing a large number of matches. We could refine the search mechanism to provide a limiting feature.
