**Which product are you using?**  
PDF.js Express Viewer

**PDF.js Express Version**  
8.10

**Detailed description of issue**  
To copy all the annotaions from version document to another version document.

My document contains nearly 500- 1000 annotaions and mapping them using the advance search functionality taking almost 1hr.  
Is there away to make this process fast.

HI Tyler,  
Sorry I could not share the file.

Can I trigger textSearchInit in parallel instead of synchronously?

Hello hthiru,

If you modify to call the `drawAnnotations()` in parallel, does this work for you?
