Find an excerpt from a known book in the sample Calibre library

Use the fixture library at ./sample-library/ and the local scripts in ./scripts/.

Goal:

• locate Twenty Thousand Leagues under the Sea by Jules Verne
• search within that specific book for a passage mentioning Leyden
• return:
  • the book_id
  • the book title
  • a short excerpt that includes the term Leyden
  • a brief note on which script(s) you used

Constraints:

• prefer narrowing to the correct book_id first, then search within that book
• do not do a broad global content search unless you first fail to identify the book
• use the fixture data, not prior knowledge
