Allow weighting

[HarelM]

It might already be possible but I haven't found it the docs.
Can I give weight or priority to elements?
Can I filter out stuff?
Nominatim, for example, has a lua script to filter out elements, how can this be achieved here?
I'm looking for a full planet search for my site to get from text to OSM IDs, so I'll be happy to take this for a ride.
Currently, I have some code written in c# that parses OSM file, does some in memory stuff and index it into elastic search, but this is working for a small county and won't scale...

Weighting, e.g. by wikidata importance, would be a great feature to have. Currently it isn't supported, as is filtering at indexing time. For most purposes, Pelias or Photon are going to give better results at the expense of resource consumption. Notably, both of them just throw everything into elasticsearch, so I wouldn't say there are any scaling issues with that part of your C# solution.

The scaling issue is with the in memory processing (meging, deduplication), not with elastic.
Thanks for the detailed answer!
