I have many Calc ODS files and I’d like to search all of them at once for a particular word and not one by one. Can this be done?
This can be done, but I don’t think LibreOffice provides a built-in way of doing it.
You can use a search program that supports indexing of LO documents, like Recoll or DocFetcher. Or if you’re comfortable using a shell, you could use also Unoconv or Pandoc to convert the files to plaintext and grep through them.
