I'm using search-ni.cgi, because I'm a Korean(foreign language).
When I search with 'bool=and' option, I can't get correct results.
What's the matter?
Is there any method to solve this?
There are many threads about this problem. But I never saw the right way.
Help me please.

Hi Mact,
I am using search-ni.cgi too, as I am building chinese one, did you solved the problems? Could you mind to share with us?

Hi, DreamWeaver.
I don't know my method is right. But now it works.
I changed the weight of Title to 3, Description to 1, and URL to 0 in Links table. The weight of URL was 3.
I also changed the weight of Description in Category table to 0 because I do not use that field.
I changed two def files too. The permission of the files were not writable, because I made them so.
Then I reindexed. And it works.
