I think that perhaps something along PointType or IntPointField/FloatPointField would be the right answer to store things: https://lucene.apache.org/solr/guide/7_3/field-types-included-with-solr.html
On the other hand, I am not sure what "searching similar vectors" mean for you, I suspect there are different meanings. It may be something like using a dist function: https://lucene.apache.org/solr/guide/7_3/function-queries.html#dist-function Or it may be a custom similarity. The other two avenues may be Learning-to-rank: https://lucene.apache.org/solr/7_3_0/solr-ltr/index.html https://lucene.apache.org/solr/guide/7_3/learning-to-rank.html Or streaming expressions https://lucene.apache.org/solr/guide/7_3/streaming-expressions.html (the documentation is lagging a bit, as individual evaluators are developed very quickly....) I haven't seen any examples in the wild using the above, which is why I am a bit hesitant. So, I suspect some further digging would be needed. And I have a feeling that each of the approaches above are not cross-linked, so you really need to be clear on what those vectors are for you and what 'search' means. Regards, Alex P.s. If you do get it to work, a follow-up summary email would be fantastic resources for others searching this kind of information later.
