ACHE is a web crawler for domain-specific search.
We are pleased to announce version 0.15.0 of ACHE Crawler!
This version includes several dependency updates and fixes a robots.txt serialization bug that only happens when the robots.txt feature is enabled. This fix may cause data backward incompatibility of previous crawls that use robots.txt. We also plan to upgrade Elasticsearch support in the next version, so this version may be the last version to support legacy Elasticsearch versions (e.g., <6.x).
