Hi, the only way to get this performance wise effective would be the approach by Adrien.
What you generally do is to index the same information into 2 different fields (in Solr or Elasticsearch as "copy_to / copyfield") with different analyzers. During query you choosse the field applicable. If you want to have "per document" scoring factors (not per term), you can also use additional DocValues fields with per-document factors and you can use a function query (e.g. using expressions module) to modify the score.
