rank.by descriptor

You can use the raw image descriptor data that was created by pixolution flow to search for similar images. The image descriptor itself can be retrieved from the index via q=id:123&fl=pxl_imagedescriptor. Solr will return a string representation of the image descriptor that you can use as input for rank.by queries.

Example for searching with a precalculated image descriptor:

&pixolution=true&rank.by=descriptor:gCCB7vjKBy8NxtwNNRT7/+waDhTqCBIh7voW+PobGf3y6vYfJAkCCBPj/O4CFPDfAAYXBvH18QMA8gnvD/3+A4AAzfiOzciRhauG2YOZmIeDypi/gBD2AgUR6/om2fcL6Pj1BPuPqs/OAJCvnaLam5OjiZi2ioAxAACAQCYQaQYyRQJ3UERjVVkMXA8=

The image descriptor must be percent-encoded (like URLs) to properly transfer and decode it.

Note: The example image descriptor in the listing above might be incompatible to your pixolution flow version. To test this functionality, please use image descriptors created by your instance.
