@Incheonkirin this looks good to me; thank you much for the docs update. I'll wait a bit in case the docs folks want to comment but otherwise will merge this shortly. |

@john-wagster @Incheonkirin docs here - this is ok to merge. this is not the best spot for a big warning, but the page would need to be restructured a bit to make a better spot available - not worth the effort vs. getting this info in. |

Thanks @john-wagster and @shainaraskas for the quick review and merge — agreed that getting the caveat documented matters more than its placement here. |

Adds a warning to the
nori_part_of_speechtoken filter docs: the defaultstoptagsincludeXPN, so a meaning-carrying Korean prefix emitted asXPNis removed by the defaultnorianalyzer. For example,비급여(non-covered) is analyzed as급여(covered), so the index cannot distinguish the two.The warning shows the
_analyzeoutput and two remedies: registering such terms viauser_dictionary_rules(preserves the full term as a single noun token), or defining a customstoptagslist that omitsXPN(preserves prefix tokens, with possible prefix noise).Closes #151094.
