Assuming I have an index of documents where any document can be one of 12 languages.
therefore I have fields like
sw_categories, da_categories (arrays with their own fields sw_category, da_category...)
obviously any document has only the fields relevant to its language.
If I am doing a multi-field query then I have basically a query with 36 possible fields.
There can then be performance issues related to query size, I am wondering if there are performance issues related to, for example all the sw_ fields needing to be queried in documents where there are only da_ fields?
I'm just wondering about this because whenever someone wants to handle multiple language indexes, it seems the suggestion is to make a field for each language - it doesn't seem like that solution would scale beyond a few languages so I would like to know before I start off on that path.
