There is a page about CJK support when using DB related search (https://docs.mattermost.com/administration-guide/configure/enabling-chinese-japanese-korean-search.html) that mentions ES and OS options. Maybe we could mention and link to the specific location where CJK support and flag is explained?

@carlisgg - How's it lookin' now? |
|
@carlisgg - Could I ask for your help with one more review on this one? If it looks good, I'll pass to Eric for merge. |
|
@Combs7th there are unintended changes in here (desktop stuff). |

Good catch @esethna, thanks! Ready for review again now. |

| Available from Mattermost v11.6. All required analyzer plugins must be installed on the Elasticsearch or AWS OpenSearch server before enabling this setting. See the :doc:`Elasticsearch setup </administration-guide/scale/elasticsearch-setup>` and :doc:`AWS OpenSearch setup </administration-guide/scale/opensearch-setup>` documentation for plugin installation instructions. |

this is great, just one last detail. The setting can be enabled even if plugins are not installed but with no effect apart from a warning being written to the logs about the fact. Also it will work with whatever plugins are installed and make sense for current deployment not requiring all to be installed, even though description is ok, maybe could be confusing.
So maybe we could rephrase
All required analyzer plugins must be installed on the Elasticsearch or AWS OpenSearch server before enabling this setting
to something like
The required analyzer plugins should be installed on the Elasticsearch or AWS OpenSearch server before enabling this setting for full analysis support. If no plugin is detected, a warning will be logged
or similar

Thanks @carlisgg! Great feedback. That wording has been updated on the draft.

@john-combs This is incorrect. Changes to the desktop release docs should not be removed as they are valid release notes as seen on current production https://docs.mattermost.com/product-overview/desktop-app-changelog.html.

@Combs7th see Amy's comments. There are still unintended desktop changelog and release docs changes in here |

1917-1919:⚠️ Potential issue | 🟡 MinorClarify plugin prerequisite wording to avoid conflicting guidance
Line 1917 says plugins “must be installed” before enabling, but Line 1933 explains the setting can still be enabled and logs a warning when no plugin is detected. Please make this wording consistent with the fallback behaviour.

In
`@source/administration-guide/configure/environment-configuration-settings.rst`:
- Line 1935: The sentence referencing only Elasticsearch should include a
parallel internal link to AWS OpenSearch; update the text that currently
contains ":doc:`Elasticsearch setup
</administration-guide/scale/elasticsearch-setup>`" to also reference the
OpenSearch guide using the same internal link syntax (for example add ":doc:`AWS
OpenSearch setup </administration-guide/scale/opensearch-setup>`"), so admins
using either backend are directed to the correct purge-and-rebuild instructions.
- Around line 1931-1936: Replace the current ".. note::" admonition with an "..
important::" admonition for the block that contains the sentence "If you enable
this setting on a server that was previously running Elasticsearch or AWS
OpenSearch, you must purge and rebuild the search indexes for existing content
to be properly searchable with the new analyzers." (locate the ".. note::"
directive and that exact sentence), leaving the content intact but using "..
important::" to mark this as a mandatory reindex prerequisite per the
documentation guidelines.
In `@source/administration-guide/scale/elasticsearch-setup.rst`:
- Around line 71-78: Add explicit operational steps after the plugin
installation block: instruct operators to restart the Elasticsearch service so
newly installed plugins (analysis-nori, analysis-kuromoji, analysis-smartcn) are
loaded, and add a clear warning that when turning on the EnableCJKAnalyzers
setting existing indexes must be purged and rebuilt (reindex) to avoid search
inconsistencies; reference the EnableCJKAnalyzers setting and the three plugin
names so readers can locate the guidance and perform restart + reindex on
production servers.
- Around line 71-72: Split the long sentence into two clear steps: first, state
that for better Korean, Japanese, or Chinese search you should install one or
more language analyzer plugins and list the plugin names (analysis-nori,
analysis-kuromoji, analysis-smartcn) and specify the exact command to run
(elasticsearch-plugin install <plugin-name>); second, instruct readers to enable
the EnableCJKAnalyzers configuration setting and reference the Enabling Chinese,
Japanese, and Korean Search doc for additional configuration options. Ensure the
two sentences are short and procedural (install plugins via elasticsearch-plugin
install <plugin-name>; then enable EnableCJKAnalyzers) and remove the phrase
"using the same ... command" that implies a prior command.
In `@source/administration-guide/scale/opensearch-setup.rst`:
- Around line 101-108: After the plugin install commands for
analysis-nori/analysis-kuromoji/analysis-smartcn, add a note instructing
operators to restart the OpenSearch service so the plugins are loaded (e.g.,
restart opensearch process/service), and add a clear warning that enabling the
EnableCJKAnalyzers setting requires purging and rebuilding existing search
indexes on affected nodes to avoid inconsistent/incorrect search results;
reference the EnableCJKAnalyzers setting name and the installed plugin names
(analysis-nori, analysis-kuromoji, analysis-smartcn) so readers know this
applies when they enable CJK analyzers.
- Around line 101-102: The sentence is a run-on mixing explanation and steps;
split it into a short purpose sentence (e.g., "To improve search for Korean,
Japanese, or Chinese content, install language-specific CJK analyzers.")
followed by a procedural sentence instructing to install one or more plugins
with the opensearch-plugin install command (list the plugin names analysis-nori,
analysis-kuromoji, analysis-smartcn), then a final instruction to enable the
EnableCJKAnalyzers configuration setting and refer to the Enabling Chinese,
Japanese, and Korean Search document for additional options.
In `@source/product-overview/desktop-app-changelog.md`:
- Line 209: The Download Binaries link currently points to
".../releases/v5.13.2" (the line reading "**Download Binaries:** [Mattermost
Desktop on GitHub](https://github.com/mattermost/desktop/releases/v5.13.2)")
which is inconsistent with the documented latest v5.13 patch; update that URL to
the correct patch (e.g., change v5.13.2 to v5.13.5 or to whichever latest v5.13
patch you intend) and verify the same link/version is used consistently across
the desktop docs pages.
In `@source/product-overview/mattermost-desktop-releases.md`:
- Line 23: The v5.13 release row was unintentionally downgraded to v5.13.4;
update the v5.13 row to reference the correct v5.13.5 artifacts by changing the
download link and tag text from v5.13.4 to v5.13.5 and the SBOM download
URL/filename from sbom-desktop-v5.13.4.json to sbom-desktop-v5.13.5.json (i.e.,
restore the v5.13 row to point to v5.13.5).
