Release 1.8.0

Although this is a new minor version release it is fully compatible with former versions.

New Features

Universal Connector

The Universal Connector enables you to connect visual search to any existing third party search engine like Elastic Search, MySQL or others. The idea is to generate a search set of image IDs in an existing search engine and pass the image ID list for visual search tasks to pixolution for Apache Solr. Instead of using pixolution flow as a standalone search system it is now possible to connect its visual search capabilities with an existing system using the Universal Connector.

The Universal Connector ships with a dedicated cache to boost internal docId lookups.

Optimizations

Empty result when Feature not found

When doing a similarity search with rank.by=id and the specified document has no feature, an exception was thrown.

To be more consistent in behaviour with former changes, pixolution flow does now returns an empty result set instead of throwing an exception.
