Using Hierarchical Fields
Original question from
Each document I index has an array of categories which looks like the following example....
Anyway, there's a couple things I'm trying to deal with.
1- The fact that we have an undefined array size. I can't just shove
these into a single field. I could explode them into multiple fields on
the fly like category_1, category_2. etc. etc
2- The fact that a search will need to be performed like "category:/Science/Medicine/*" would need to return all items within that category.

Note: Be careful of the analyzer you use.
Could you put them all into a tab-delimited string and store that as a single field, then use a TabTokenizer on the field to search?
