Hello,

Is it possible to launch a query "X", and have the results persisted/cached/saved so that I may write a new query "Y" with definition (query X AND filter Z) so that it uses the results from query X to speed up the retrieval?

I am aware of reindex API, but this duplicates the data. I was hoping for a lighter/more elegant solution.

We were considering doing this because we have hierarchical relationships between our documents and we were looking to find a way to "store" higher-level documents for which the queries matched the lower-level documents. The idea is to then use the higher-level documents that were the result of the first query as a filter for further queries.

If anyone has any suggestions, we would greatly appreciate it.
