LoadURLInfo loads
user-defined section
values from the urlinfo table,
so they can be displayed in search results using methods
RESULT::document_property() and
RESULT::document_property_html().
The default value is yes, which means that the user-defined section values are available for displaying in search results.
If you don't need user-defined section values to be displayed in search results, you can set LoadURLInfo to no to get better performance.
