Just written in few days because of old Yacy server not available.

Lighweight solution that plan to improve soon (images crawling plus some ideas about distributed data API or maybe the DB sharing, because builded on sqlite and FTS5 indexer)

Today is first day of scan begining, so sorry if some bugs there available - please write here or in project issues
