I use the calendar as a billling tool as well - have my business records in the calendar, search for customers, and then could easily transfer the entries to a spreadsheet to write a bill.

Unluckily, I can neiter select multible entries in the search results list, not copy them to the clipboard, not export them e.g. as a csv list. I'd appreciate such a feature very much.  

Reproducible: Always



Expected Results:  
Can select multiple search result list entries and copy them to the clipboard - or have a csv export option (best is to have both).
