What is Out of order word insertion?

[ayush-sharma]

While populating a pre-built index I'm getting the following error:

Uncaught Error: Out of order word insertion
    insert https://unpkg.com/lunr/lunr.js:1771
    load https://unpkg.com/lunr/lunr.js:2305
    <anonymous> http://localhost:4000/static/js/script-search.js:89
    EventListener.handleEvent* http://localhost:4000/static/js/script-search.js:80

The code I'm using to populate the index:

var idx = lunr.Index.load(JSON.parse(window.my_big_index));

I wasn't able to find any info googling around.
What does this error mean, and what's the best way to fix it?

Thanks.

Hi all,

I'm still unable to diagnose this issue, and I'm trying random things since I don't know what its about.

Any ideas?
