Indexing Resources

Menu option: Options > Preferences > Indexing resources

Memory
If you find that dtSearch is using too much memory during index updates, you can specify a limit here on the number of megabytes of memory that dtSearch may use.  With more memory, dtSearch will be able to build indexes more quickly. 

Temporary files
Use this setting to control the location of temporary files created during indexing.  If no location is specified, temporary files will be created in the index folder.

Cancel index update if dtSearch estimates there is not enough disk space available
dtSearch can estimate how much space it will take to complete an index update and alert you if there is not enough free space available.  If this box is not checked, dtSearch will attempt to build the index and will only halt the update when the disk is full.

Automatically use the 64-bit indexer when possible
The 64-bit indexer is faster and can use more memory, so it is usually preferable to use it when building indexes.  Check this box to have dtSearch automatically detect cases where the 64-bit indexer can be used instead of the 32-bit indexer.

Store a copy of indexed Outlook items in the index
When you index Outlook data, dtSearch uses Outlook to access items in your message store.  If dtSearch stores Outlook items in your index, then after a search dtSearch can display retrieved message items without the need to go back to Outlook to extract them.  

Ask Windows to keep computer awake during indexing
If you find that scheduled index updates are not completing on time due to Windows power management, you can use this setting to prevent your computer from going to sleep automatically while an index is being updated.  dtSearch will use the Windows power management API to advise that the computer is working and should not be put into a sleep state automatically.

Index using multiple threads
On 64-bit Windows computers with multiple cores and at least 16 Gb of memory, dtSearch can use a new multi-threaded indexing process to greatly improve indexing speed.  This is a preview feature and is not currently recommended for production work.
