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...
