I am trying to understand how to build a lucene index for data that has a 1 to many relation.
suppose I have a table for families with id and family name
and a table of people with id, first name, and hobbies (which is free text).
how would I create a lucene index that will help me find families that have family members that their hobbies match the search query (as full text search) ?
I want to get each matching family just once (even if there are several family members that their hobbies are a hit for the query.
What If I also had a hobbies field on the family record it self (in addition to personal hobbies) and I wanted to get all the families that either match on the family hobby or on the hobby of on of the family members ?
You may treat families as documents that are composed of hobbies (terms). Index hobbies in a searchable field, no matter they are family hobbies or personal hobbies. For the rest of the fields just store them as additional fields.
