Here is my experience of getting a good search relevancy: pre processing is
paramount. Pre process your data and using perl is much powerful and flexible
then putting all the logic in a customized analyzer. And if you want to search
multiple fields, create a field called "all" and cat all the data there. It is
much better than using MultiFieldQuery. MultiFieldQuery just permutates your
query with all default fields. If you have more than 3 default fields, the
query starts to look unnecessarily complex. However, there is one case that
MultiFieldQuery is needed: if you can't use the same tokenizer/analyzer for all
default fields.

Subject: search in all fields
Hi all:
I study Lucene and I want build search on all the fields, I find
MultiFieldQueryParser can search on multiple fields, but we must specify
fields. maybe we can add a field named all_field that contain all the fields
when indexing, but it make the index file larger.
so how to make search on all fields without specify any fields ?
Appreciate your help!
