Search Appliance
The following table summarizes the trade-offs for the new and refresh rewalk types.
| Method | Advantages | Disadvantages |
New | Guarantees most accurate representation of current site. | Uses more bandwidth and temporary disk space. |
| Does not disturb live search database. | Longer time before site changes are reflected in live search. | |
Refresh, Refresh All, or Singles Only | Faster. | Could get out of sync with actual site under rare circumstances. |
| Uses less bandwidth and temporary disk space. | A lot of changed pages could substantially slow searches during the walk. | |
| Site changes are reflected in live search much sooner. | Works best with If-Modified-Since support on walked web server. | |
