@easyops-cn/docusaurus-search-local

An offline/local search plugin/theme for Docusaurus v2/v3, which supports multiple languages, especially optimized for language of zh.

Originally forked from cmfcmf/docusaurus-search-local.

Then later fully rewritten with TypeScript 💪, styles polished 💅, language of Chinese supported 🇨🇳, and tests covered ✅.

    [
      require.resolve("@easyops-cn/docusaurus-search-local"),

      ({
        // ... Your options.

        hashed: true,
        // For Docs using Chinese, The `language` is recommended to set to:
        // ```
        // language: ["en", "zh"],

      }),
    ],
  ],
};

Notice: We present this as a theme instead of plugin now, see this comment.

Theme Options

Name	Type	Default	Description
indexDocs	boolean	`true`	Whether to index docs.
indexBlog	boolean	`true`	Whether to index blog.
indexPages	boolean	`false`	Whether to index pages.
docsRouteBasePath	string \| string[]	`"/docs"`	Base route path(s) of docs. Slash at beginning is not required. Note: for docs-only mode, this needs to be the same as `routeBasePath` in your `@docusaurus/preset-classic` config e.g., `"/"`.
blogRouteBasePath	string \| string[]	`"/blog"`	Base route path(s) of blog. Slash at beginning is not required.
language	string \| string[]	`"en"`	All lunr-languages supported languages, + `zh` 🔥.
hashed	boolean \| `"filename"` \| `"query"`	`false`	Whether to add a hashed query when fetching index (based on the content hash of all indexed `*.md` in `docsDir` and `blogDir` if applicable). Setting to `"filename"` will save hash in filename instead of query.
docsDir	string \| string[]	`"docs"`	The dir(s) of docs to get the content hash, it's relative to the dir of your project.
blogDir	string \| string[]	`"blog"`	Just like the `docsDir` but applied to blog.
removeDefaultStopWordFilter	boolean	`false`	Sometimes people (E.g., us) want to keep the English stop words as indexed, since they maybe are relevant in programming docs.
removeDefaultStemmer	boolean	`false`	Enable this if you want to be able to search for any partial word at the cost of search performance.
highlightSearchTermsOnTargetPage	boolean	`false`	Highlight search terms on target page.
searchResultLimits	number	`8`	Limit the search results.
searchResultContextMaxLength	number	`50`	Set the max length of characters of each search result to show.
explicitSearchResultPath	boolean	`false`	Whether an explicit path to a heading should be presented on a suggestion template.
ignoreFiles	string \| RegExp \| (string \| RegExp)[]	`[]`	Set the match rules to ignore some routes. Put a string if you want an exact match, or put a regex if you want a partial match. Note: without the website base url.
ignoreCssSelectors	string \| string[]	`[]`	A list of css selectors to ignore when indexing each page.
searchBarShortcut	boolean	`true`	Whether to enable keyboard shortcut to focus in search bar.
searchBarShortcutHint	boolean	`true`	Whether to show keyboard shortcut hint in search bar. Disable it if you need to hide the hint while shortcut is still enabled.
searchBarPosition	`"auto"` \| `"left"` \| `"right"`	`"auto"`	The side of the navbar the search bar should appear on. By default, it will try to autodetect based on your docusaurus config according to the docs.
docsPluginIdForPreferredVersion	string		When you're using multi-instance of docs, set the docs plugin id which you'd like to check the preferred version with, for the search index.
zhUserDict	string		Provide your custom dict for language of zh, see here
zhUserDictPath	string		Provide the file path to your custom dict for language of zh, E.g.: `path.resolve("./src/zh-dict.txt")`
searchContextByPaths	`(string \| { label: string \| Record<string, string>; path: string; } )[]`	`[]`	Provide an list of sub-paths as separate search context, E.g.: `["docs", "community", "legacy/resources"]`. It will create multiple search indexes by these paths.
hideSearchBarWithNoSearchContext	boolean	`false`	Whether to hide the search bar when no search context was matched. By default, if `searchContextByPaths` is set, pages which are not matched with it will be considered as with a search context of ROOT. By setting `hideSearchBarWithNoSearchContext: true`, these pages will be considered as with NO search context, and the search bar will be hidden.
useAllContextsWithNoSearchContext	boolean	`false`	Whether to show results from all the contexts if no context is provided. This option should not be used with `hideSearchBarWithNoSearchContext: true` as this would show results when there is no search context. This will duplicate indexes and might have a performance cost depending on the index sizes.
`forceIgnoreNoIndex`	boolean	`false`	Force enable search index even if `noIndex: true` is set, this also affects unlisted articles.

I18N

Since v0.25.0, we support docusaurus i18n system, and provided en / de / vi and zh-CN translations out of the box.

For other languages, please follow the official tutorial about how to translate plugin data. And translate theme.SearchBar.* and theme.SearchPage.* in i18n/*/code.json.

Translations by options is dropped since v0.25.0.

See translation options for <0.25.0

To make this theme localized, pass a `translations` option which defaults to:

{
  "translations": {
    "search_placeholder": "Search",
    "see_all_results": "See all results",
    "no_results": "No results.",
    "search_results_for": "Search results for \"{{ keyword }}\"",
    "search_the_documentation": "Search the documentation",
    "count_documents_found": "{{ count }} document found",
    "count_documents_found_plural": "{{ count }} documents found",
    "no_documents_were_found": "No documents were found"
  }
}

Note that *_plural can be omitted if it is the same as singular.
