$3


The fields config property is passed into Lunr directly as field attributes, and can be used to configure the relative priority of different field types (e.g. title, content, keywords).

docusaurus-lunr-search sets the default value for fields to:

`javascript
{
title: { boost: 200 },
content: { boost: 2 },
keywords: { boost: 100 }
}
`

Indexing non-direct children headings of .markdown


By default, this library will only search for headings that are
direct children of the .markdown element.

If you would like to render content inside the .markdown element on
a swizzled DocItem component, and want this library to **index the
headings inside those custom elements even if they are not direct
children of the .markdown element**, then add the attribute
data-search-children to a parent element of the headings you want to
index.

The data-search-children attribute will cause this library to look
for all headings inside that element, including both direct and
indirect children (E.g. 'grandchildren' nodes).

Check this issue #115 for more details.

Upgrading from docusaurus V2 to V3


Update the docusaurus-lunr-search version to 3.3.0 or higher in package.json file

Remove src/theme/SearchBar folder if you swizzled it before, if the folder does not exist then ignore this step.

Do yarn install or npm install

If npm install fails to install with error unable to resolve dependency tree, run npm i --legacy-peer-deps

Credits

Thanks to algolia/docsearch.js`, I modified it to create this search component

And thanks cmfcmf, I used the code from his library docusaurus-search-local for multi-language support.
