Why do I get an error when reading the search_index.json file?

[RemyYYZ]

My search_index.json

Error

It has been confirmed that there is "1.21" text content in search_index.json, but no search results are displayed

But when I try to delete some text in search_index.json, it can be read normally

So is this because the search_index.json file is too large?
