to OR or not

[Amol Bhutada <Am...@synechron.com>]

Hi everybody,
I am using lucene in almost every web application I am working on. It's simply a great software.
I have developed an advanced search with Lucene 1.4. Now I am looking for developing a fuzzy search i.e get one search string from the user and search across all fields of member documents. 

I can think of two options :
- form a OR query using given search string for all fields
- add one more field ( say keyword ) to the member document with all information of the user.

- Are there any other options ?
- Which will be a better option for the system which has arround one million documents each having 20 fields and performance is a major concern?

thanks
Amol

I much prefer the one catch-all field approach, personally.  As long  
as scoring works out how you'd like using this technique, then it'll  
make for simpler (and thus faster) queries.  However, reindexing is  
necessary to bring another field into the mix, whereas run-time ORing  
is more flexible and dynamically adjustable.
