Designing the Application
Figure 15. Mapping object type attributes to columns in which search results are displayed
Each searchable attribute and column in which the search result is displayed adds load to the system.
Design search forms with as few searchable attributes and results columns as possible.
Wherever possible, use single-value attributes instead of repeating value attributes. TaskSpace
combines all single value attributes into a single query, but issues an additional query for each
repeating attribute. Each additional query affects performance.
Include the following attributes in your search form. Mark the attributes invisible unless they must
be visible for business purposes.
• r_lock_owner
• a_content_type
• r_content_size
• r_object_type
• r_object_id
If these attributes are not present in the search query of the form, TaskSpace performs a full fetch of
the object to retrieve the attributes, which affects performance.
Using search criteria
The search template, task list template, folder contents template, and process instance list template
include a screen, like the one shown in Figure 16, page 44 for the search template, to specify search
criteria for each item selected for display in a results column.
