Adding a search function to a lookup column?

Question

Situation:

• I have a list and a library.

• The list has a lookup column that allows you to choose multiple documents from the library.

Problem:

• The library has several hundred documents, so it's very difficult to find the right document(s) to add to the list item.

Is there any way I can implement a search function above the list of documents so the list filters dynamically as I start typing the beginning of the document reference?

I have yet to find a proper solution to this problem and I need to avoid using SharePoint Designer for maintenance reasons if at all possible.

I believe your requirements can be met by the PnP Search modern webparts

https://github.com/SharePoint/sp-dev-fx-webparts

For your situation, I would create a new page with these Search web parts configured with a custom Result Source pointing to the Document library. If you go into site settings => Search Result Sources => New Result Source => Launch Query Builder. You can create a source that points to the Document Library

{searchTerms} path:https://<tenant>.sharepoint.com/sites/yoursite/Shared%20Documents -ContentTypeId:0x0120* -ContentClass:STS_List_* -FileExtension:aspx

Once you click save, go back into the new Result source and copy the GUID from the URL. You can then paste this GUID into the 'Result Source Identifier' in your Search Verticals webpart

You'll have to add 'Search Box', 'Search Verticals' and 'Search Results' for this to work
