### Translations

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

```json
{
  "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.

## Custom Styles

This plugin is shipped with polished styles just like the Algolia Search on the Docusaurus v2 website. Feel free to override these css custom properties (css variables) below.

## Trouble Shooting

When building your docs project, Set the env `DEBUG=search-local:*` to enable [debug](https://github.com/visionmedia/debug) logs.

```shell
# In your docs project:
DEBUG=search-local:* yarn build
```

In case some specific errors occurred:

- `Error: Cannot mix different versions of joi schemas`:
  - Try using @easyops-cn/docusaurus-search-local >= v0.16.0 with Docusaurus >= v2.0.0-alpha.73
  - Try using @easyops-cn/docusaurus-search-local between v0.14.0 and v0.15.1 with Docusaurus between v2.0.0-alpha.68 and v2.0.0-alpha.72
  - Or try using @easyops-cn/docusaurus-search-local <= v0.13.1 with Docusaurus <= v2.0.0-alpha.66
- `Error: Command failed with signal "SIGSEGV"`:
  - This is probably caused by a [known issue](https://github.com/yanyiwu/nodejieba/issues/187) introduced by `nodejieba@2.5.2`, if you enabled language of zh.
  - Try downgrading `nodejieba` to `2.4.2` and it will work again, see discussions in [#47](https://github.com/easyops-cn/docusaurus-search-local/issues/47).
