Presorting documents before a reindex
By default, Perceptive Search indexes your documents in the order they appear in the file
system directory. You can choose to presort your documents prior to updating,
instead of using the order of the file system directory or directories in which
they appear.
Presorting the result list can result in faster querying as you may not need to
sort the result list. Presorting affects the order by which documents are added
to the index. You can then use Default Sort order at query time to see
the documents in the same order, this can save processing time as a second level
sort is not required.
Presorting applies only to a reindex. To perform a presorted reindex:
- Start Perceptive Enterprise Search - Local Administration Console
- Open the index you wish to modify, you can do this by either:
- Selecting it from the My Index Catalog list
- Select File > Open an Index from the menu and browse to the location
where the index is stored
- From the menu, select Index > Reindex
- Click the Presort button, the following options are available:
- No presorting
- By date
- Alphabetic, by filename
- Reverse alphabetic, by filename
- Alphabetic, by full file path
- Reverse alphabetic, by full file path
Choose your option and click OK.
- You can log the output of a reindex by clicking the Log button.
- Click OK to begin the reindex.
