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
