Search indexing does not work if some links are broken

[kokovtsev]

Description

Indexing for the search plugin fails if any document linked in the sidebar failed to load.

Expected behavior

Docsify should index at least pages that were loaded successfully.

Actual behavior

The index is not updated at all

Steps to reproduce

Please see this reproduction repository. In this repo, the sidebar has a link that is intentionally broken, i.e. leads to a non-existing MD file.

• run yarn
• run yarn serve
• navigate to http://localhost:3000/
• try to search for "ipsum"

Normally, Docsify should find this word in the "lorem.md" file. However, it says "No results" because it failed to index the content.

Environment

• Docsify version: 5.0.0-rc.3

Additional Information

• Bug still occurs when all/other plugins are disabled?
