# Bookologia Indices Dataset |
|
|
|
|
|
Bookologia is a specialized search engine of books, to find any book within seconds. |
|
|
This dataset contains three Elasticsearch indices extracted from Bookologia database: **authors_data**, **book_links**, and **books_data_bis**. |
|
|
Each index stores structured metadata relevant to authors, books, and associated resources. |
|
|
This dump is suitable for tasks involving metadata analysis, author-book linking, recommendation systems, or search enhancement. |

- Some fields like ratings and reviews in authors_data are stored as text, not numeric, so cast carefully. |
