The Logos indexer process explained.
What does the Indexer do?
The Logos Indexer powers the Logos Search Engine by building a single, custom, index of everything in your specific library. Essential to finding results in every resource in your library, the Logos Indexer enables much broader searches to finish much faster than in Logos 3 or its predecessors.
It allows search results to show you the top hits ranked by number and relevance. When new books or updates are added to your library, the index will also be updated automatically to know the position of every word in those resources. This may take a long time when you first install Logos, but subsequent updates should occur very quickly.
Frequently Asked Questions
Q. What if I add a new book?
A. Your new book will be indexed by itself, then merged into the main index. This is typically much faster than building the initial index.
Q. Is there a way to pause indexing?
A. Yes. There is an option to pause the indexing process for 4 hours at a time. This is done by right clicking on the Logos Indexer icon that appears in the System Tray (by your computer's clock and internet connection icons).
Logos 5 Indexer icon:
Logos 4 Indexer Icon:
Mac Users will see the Logos 4 Indexer icon for either version.
Pausing the indexer will prevent it from processing more information, reducing the strain on your system resources, but does not free up memory that is already in use. You can avoid this by indexing over night instead (see tips below).
Q. Can I speed it up?
A. You might try temporarily pausing your anti-virus or backup software.
Indexing speed is also affected by the amount of memory available and the speed of your hard drive. Upgrading to more "RAM" memory or a "Solid State Drive" hard drive may increase indexing speed significantly on some systems.

- Be sure not to put your computer to sleep (hibernate) while Indexing. This includes not closing the lid if you're using a Laptop or Macbook.
- Try not to use your computer while Indexing. Using your computer will not harm the index, but it will slow the process depending on how many system resources are being used by additional tasks.
- To reduce the amount of study-time spent indexing, you may want to restart Logos in the evening, so that it has a chance to install updates and index them over night, instead of while you're using the program.
Indexing is generally a very smooth process, but occasionally errors can occur, especially if the process has been interrupted. You may receive the following message:
"Logos Bible Software Indexer has encountered a problem and needs to close"
please try the following:
- Open the Logos Applocation window.
- Click into the "Command" box at the top of the window.
- Enter the command: "Rebuild Index".
The indexer should begin rebuilding your index immediately. This may take several hours for large libraries.
Indexing is taking too long:
Indexing time can vary by computer and size of library. It may take a few hours to complete. During this time, it is important to leave your computer running. Do not set it to "sleep" or "hibernate", turn it off or restart it. If you're using a laptop, be sure to leave the lid open and the power cable plugged in.
If interrupted, it will need to start over. If you feel it has stalled, please use the Rebuild Index command above.
