I'll have to recreate my setup again since I tried re-building solr without
some PRs and it wiped everything out(my mistake!)
I was able to get the query Solr sends for search KnnFloatVectorQuery vs
what it uses for getting the
score {AbstractKnnVectorQuery$DocAndScoreQuery. This might give some
breadcrumbs to Mike while I try to look into it more tomorrow
query = {KnnFloatVectorQuery@10048}
"KnnFloatVectorQuery:value[0.1234,...][160000]"
target = {float[768]@10064} [...
field = "value"
k = 160000
filter = null
isDeprecatedRewriteMethodOverridden = false
CLASS_NAME_HASH = 1536329572
query = {AbstractKnnVectorQuery$DocAndScoreQuery@10074}
"DocAndScore[160000]"
k = 160000
docs = {int[160000]@10084} [... more]
scores = {float[160000]@10085} [...]
contextIdentity = {Object@10087}
isDeprecatedRewriteMethodOverridden = false
CLASS_NAME_HASH = 1706435309
