How Can I Trim My X1 Search Index?

If your index is larger than the space on your hard drive allows, or you simply want to have a smaller, more manageable index, you can trim the amount of data in your index. Suggestions for trimming the index include:

  • Edit the various Outlook Data sources (Email, Contacts, Calendar, Task) to remove any folders that you might not really need to search.  If you do not have Outlook Task or other Outlook items to index, you might consider setting those areas to Never Repeat the index.
  • Edit the File Data Source and remove any disks or folders that you're not likely to need to search. This includes especially the C:\ProgramData, C:\Program Files, and C:\Windows directories, as well as the Temp folder (C:\Users\<username>\AppData\Local\X1 Search and the location of your X1 index files (Menu > Options > Index [tab] for location).
  • If your Files indexing level is set to "Everything" (the checkmark), consider switching to the next lower index level (the "glass 3/4 full" setting), or the "Sandwich" setting (green on top - white in the middle - green on bottom).

    The Everything setting performs full content indexing for all files X1 Search finds on the disk, oftentimes unnecessarily indexing files you'll likely never need to search (the internal content of an executable file or .dll, or a shortcut link file as an example).

    Going with the "glass 3/4 full setting" still gives you full content indexing for the files active in our Global Whitelist Settings (see button with that name) and gives you Metadata indexing (file name, size, etc.) of files on the disk that are not set for content indexing.  If you don't care about searching the file types that are unchecked in our specified files list, try the Sandwich setting which focuses only on the selected file types and provides full content indexing for those file types.

    Both the 3/4 full setting and the Sandwich setting leave X1 very flexible in regard to your search usage while requiring a smaller and potentially more manageable index on disk.
