Keyword Search

Keyword Search enables users to search concepts with keyword. As Figure 2 Keyword Search portion suggested, users can setup many searching parameters to better the relevancy of the returning results. User can input keywords into the Term field, Scope Note field, or both. Also user can set the parameters of the keyword inputs. For Term and Scope Note keyword, the parameters supported are "Must have", "Or have", and "Not have". For Broader Concept, however, the parameters supported are "Must have" and "Not have". To avoid input errors when providing Broader Concept keyword, ConceptChoir provide a mini browser for user to select desired concept rather than input its label manually. To open mini browser, simply click button to open the mini browser to make a selection. Users can also set the searching language and scope by selecting from the Language dropdown menu and Search in dropdown menus.

After setting up all search parameters, click the Search button to perform Keyword Search.

Concept Relationship Search

User would also need to specify the searching scope for the search by selecting from the Search in dropdown menus. After setting up the parameters, click the Search button perform Concept Relationship Search.

When a user perform any of the three searching methods ConceptChoir Advanced Search provided, ConceptChoir will first validate the user inputs and then perform search by the submitted parameters. Once the search operation is completed, ConceptChoir will automatically close the Advanced Search window and list the searching result list in the Tree Display Area of ConceptChoir's main Vocabulary Explorer. User can click any of the concepts in the list to view its detailed information from the Node Detail Area.
