My schema contains about a hundred of fields of various types (int,
strings, plain text, emails).
I was concerned what is the common practice for searching free text over
the index. Assuming there are not boosts related to field matching, these
are the options I see:
1. Index and query a "all_fields" copyField source=*
1. advantages - only one query flow against a single index.
2. disadvantage - the tokenizing is not necessarily adapted to this
kind of field, this requires more storage and memory
2. Field aliasing ( f.myalias.qf=realfield)
1. advantages - opposite from the above
2. disadvantages - a single query term would query 100 different
fields. Multi term query might be a serious performance issue.
Any common practices?
