I am currently in a development team that has implemented a search app using Flask-WhooshAlchemy. Admittedly, we did not think this completely through.
The greatest problem we face is being unable to store query results into a Flask session without serializing the data set first. The '__QueryObject' being returned via Whoosh can be JSON serialized using Marshmallow. We have gone through this route and, yes, we are able to store and manipulate the retrieved data, but at a tradeoff: initial searches will take a very long time (at least 30 seconds for larger result sets, due to serialization). For the time being, we are currently stuck with having to re-query anytime there are changes to the data set (changes that shouldn't require a fresh search, such as switching between result views and changing the number of results per page). Adding insult to injury, whoosh is probably not scalable for our purposes; Elasticsearch seems a better contender.
In short:
How can we store elasticsearch query results in a Django session so that we may be able to manipulate these results?
Any other guidance will be greatly appreciated.
If anyone cares, we finally got everything up and running and yes, it is possible to store elasticsearch query results in a Django session.
