What can I name my indices?

• You can use letters, numbers, spaces or punctuation in your index name, with the exception of the following characters: /, ~, ,, \, `, &, |, ;, $, and *.
• The index name must be less than 256 characters long.
• The index name can not end with one the following extensions:
  • .bin
  • .idx
  • .txt

Additionally, it is not a good idea to give your index a name that includes the word ad or advertisement. Eager ad blockers can see this as a red flag, making your users unable to use your search.
