Sorry to reach out to you by submitting an issue on this repository.

I saw your question on the archived thread coolwanglu/pdf2htmlEX#719 (comment)

and wanted to let you know how I solved that issue as I was having the same problem.

If you modify the js code within pdf2htmlEX.js, minify it, and replace pdf2htmlEX.min.js with that code, within the pdf2htmlEX data directory, defining:
'preload_pages' : 1000
and
'render_timeout' : 1
or whatever settings for those parameters work for you, that will solve your searching issue.

Let me know if you need any help or have a question. Also let me know when you're okay with me deleting this comment/issue on this repo.

Another seemingly more effective way is to comment the line:
this.pre_hide_pages();
