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?
And, if you need to, do a .split("\t") on the field value in order to break
them back up into individual categories.

Subject: Nested category strategy
Hey All,
I'm trying to figure out the best approach to something.
Each document I index has an array of categories which looks like the
following example....
/Science/Medicine/Serology/blood gas
/Biology/Fluids/Blood/
etc.
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.
Thanks in advance to anyone who can give me some help here.
Thanks
