Set UpdateExisting
to True
to attempt to convert incoming index actions into metadata updates when no Index or SourceType fields have been modified.
By default, when IDOL Server detects a duplicate document according to your KillDuplicates method, it deletes the existing document, and then indexes the incoming document (unless you also set KeepExisting to True
, in which case it ignores the new version). This behavior can result in a large number of disk reads and an expensive flush, even if only metadata (such as the ACL) has changed.
When you set UpdateExisting
, IDOL Server attempts to determine if the change is a simple metadata update, by checking that:
In this case, it modifies the metadata in the existing document, rather than fully indexing the new version. This option saves the disk usage required for index field processing.
