Every time you perform an update, Perceptive Enterprise Search - Local Administration Console scans all the folders which are covered by your indexing rules to determine which documents have been added, modified or deleted since the last update. It uses intelligent logic to minimize how much of the directory tree it has to scan. However the scan could take quite some time if your rules cover a large directory structure. For example you may have the following folders:
C:\2002\....
C:\2003\....
C:\2004\....
C:\2005\....
Below each main folder you may have a sub-folders for each week, yet only be adding new documents into the 2005 folder. Because Windows provides no way for Perceptive Enterprise Search - Local Administration Console to see if any changes have occurred within a folder other than by scanning through it, Perceptive Enterprise Search - Local Administration Console makes a full folder scan every time you do an update.
With the Static Folder facility, you can tell Perceptive Enterprise Search - Local Administration Console to ignore particular folders during an update, if you know those folders will not be changed. To do this, you need to amend the ISYS.CFG file.
STATIC C:\2002
STATIC C:\2003
STATIC C:\2004
Perceptive Enterprise Search - Local Administration Console will ignore these folders for scanning in the Update process. When Reindexing, however, Perceptive Enterprise Search - Local Administration Console will ignore the STATIC directive and index all documents covered by your rules. The speed saving you gain by utilizing the STATIC option depends on how many folders you have, their level of nesting, number of entries in each level and proportion of STATIC folders.
