dtSearch default alphabet file text

Note: Some of the characters in the alphabet file are not printable; screenshots were used instead of the actual text. You cannot copy or paste the Spaces or Ignore characters since they are not printable. Instead, use the dtSearchDefaultAlphabetFile instance setting to update the dtSearch default alphabet file.

Note: Each sequence must start with a leading, or empty, space. Not having the leading space may produce errors.

When you save a dtSearch index, Relativity runs a validation check on the alphabet list. You will see a warning message if Relativity detects invalid spacing or syntax. You cannot save the index if there are errors with the alphabet list. The validation check includes:

  • Header sections:

    • Header section appears first in Alphabet

    • Exact header section without any added whitespace

    • Required newline before section

  • Letters:

    • Exact title, allowing any whitespace and comments preceding double slash //

    • Each letter on own line with preceding space

    • Each letter variant separate by single space

    • Allow any extra whitespace after letter

  • Hyphens, Spaces, and Ignore

    • Exact title, allowing any whitespace

    • Single line of characters with preceding space

    • Optional newlines before next section

  • Footer sections:

    • Exact title

    • Skip validating any text following title

  • General:

    • Purple, Pink, Red, Green sections are each optional and can be in any order

Note: Previous guidance hid some characters that should not have been hidden. Those non-printable characters are critical to index function and should never be removed. The "\08" text represents the "backspace" text, and should also never be removed or split up (IE trying to index the backslash).

Note: This section only accepts ASCII characters (code points between 33 and 127) as input, we currently do not support ignoring extended Unicode values.
