Hello,
little off topic, but how did you obtain the pagerank for each page. did you
calculate it, or have you obtained it with some other way while getting a

Hello,
When you look at the fields of a document with Luke, there is a norm column.
I have not been able to figure out what that is.
The reason I am asking is that I am trying to build a uniqueness model. My
Index is structured as follows:
classID, textID, K, V
classID is a given class. textID
yes, figured it out. thanks.
how about checking for uniqueness?
Best.

Hello,
Is it possible to make a boolean query where a word is equal to fieldA or
fieldB?
in other words, I like to search a word in two fields, if word passes in
fieldA or fieldB, then it is a hit.
