**Which product are you using?**

**PDF.js Express Version** 8.7.0

**Detailed description of issue**  
When there are a lot of search results, some of them are duplicated. It is not a consistent behaviour for the same document and search string sometimes there are no duplicates, and the other times the different results are duplicated. Sometimes when I click on the duplicated search result, the original one is highlighted, sometimes not. I can provide the video of this behaviour, but I’m not sure how to upload it. On the screenshot the two search results at the beginning and end of page 4 are duplicates.

**Expected behaviour**  
All the search occurances are displayed once in the search panel.

**Does your issue happen with every document, or just one?**  
It happens on different documents. Looks like the prerequisite is lots of search results.

**Code snippet**

```javascript
documentViewer.addEventListener('documentLoaded', () => {
    instance.searchTextFull(searchQuery, { regex: true });
}

```

Hi there,

Thank you for contacting pdf.js express forums,

I was unable to reproduce this issue on our showcase: [PDF.js Viewer Demo | PDF.js Express](https://pdfjs.express/demo)

Could you please try version 8.7.2 and see if your issue is reproducible?

Or if you’re using the viewer version:

Hi there,

Using the same version you provided, I was unable to reproduce the issue (41 results):

Could you please share your full WebViewer code or a minimal sample project for us to reproduce this issue?
