It is possible to limit amount of hits per token?

[va2dim (Vadym Polietaiev)]

I have indexed refBook of materials:
doc/id name
1 polibutilen
5 polibutelenteraftalat
13 elastan,
23 elastodien,
25 elastodin

query could contain many materials (using OR operator): elastan, polibutilen.

(example data as unique in English, but real data in other language, so I am using for matching only landuage stemmer (ending could be variable in query).

As a result of search I hitted all this materials, but I need only best hit for each token (for query elastan, polibutilen, only docs 13,1).
Is it possible to set such a limit? If not what can be another way of implementation of such a logic in elasticsearch?

Hi @va2dim

Could you tell if you are using any analyzer? It would be perfect if you share your mapping/settings so that it is possible to carry out a simulation.

Example of indexed documents in russian lang:
id/doc,name
1, эластан,
2, эластодин, 
3, эластодиен 
4, полибутилен
5, полибутилентерафталат
6, акрил, 
7, акрилонитрил

Example of query in russian: 20% эластана, 80% полибутилена
