Hi, I have been looking around on the web for information on sorting by a custom function but the results are inconclusive to me and some of it seems so old that I suspect it's outdated. What I want to do is the following:
I have a field "fingerprint" in my schema that contains a binary data (e.g. 64 bytes) that can be used to compute a distance/similarity between two records. Now I want to be able to execute a query and sort its result by the distance of the matching records from a given reference value, so the query would look something like this q=*:*&sort=my_distance_func(fingerprint, 0xadet54786eguizgig) where my_distance_func is my custom function fingerprint is the field in my schema (type binary) 0xadet54786eguizgig is a reference value (byte array encoded in whatever way) to which the distance shall be computed, which differs with each query. Is ValueSourceParser the right way to look here? Is there a source code example someone can point me to? Thanks in advance, Robert
