1. Is this request related to a challenge you're experiencing? Tell me about your story.

In the knowledge base, how can I use multiple different delimiters to split a document, for example, splitting by both commas and periods at the same time? I tried the following regular expression but it didn't work: "(,|。)" ”、“，|。” 、“[，|。] ”
