"""alib.ru book-marketplace search (3.2M listings, RU+KZ sellers).
|
||
|
||
Usage: tools/alib.py "query"
|
||
|
||
Site specifics (verified 2026-07-09):
|
||
- Endpoint: https://www.alib.ru/find3.php4?tfind=<query>
|
||
- Encoding: query must be **CP1251** percent-encoded (utf8 → mojibake "РќРѕР").
|
||
- Pages are CP1251.
|
||
- Search is STEM-BASED (word matches all inflections — unlike libgen) + phrase mode with
|
||
double quotes; also author-first, year-range, ISBN-digits, price-range fields.
|
||
- Result rows: "<cat> || <Author> <Title> |Серия: ... <City> <Year> <Pages> <Binding>.
|
||
(Seller X, city.) Цена: N руб." — i.e. listings, not library records: good for
|
||
small-press / rare / out-of-print RU editions that shops don't carry.
