@dosubot[bot] commented on GitHub (Aug 28, 2024):

A lot of text may be lost when cleaning plain text DOCX files with Dify due to the preprocessing rules applied during the cleaning process. Specifically, the rules for replacing continuous spaces, newlines, and tabs, as well as deleting all URLs and email addresses, can result in significant text loss if not configured properly.

Supporting evidence from the document:

Preprocessing rules:

  • Replace continuous spaces, newlines, and tabs;
  • Delete all URLs and email addresses;

Additionally, the CleanProcessor class in Dify's codebase shows that during the extraction and transformation phases, text documents are cleaned and split according to the processing rules. This includes removing extra spaces, URLs, and emails, which can inadvertently remove or alter significant portions of the text, leading to the observed loss of content [1][2][3].
