Search with whitespaces
Hi,
I'm new to Lucene and I'm trying to do some stuff with Lucene but I have
some problems.
I have some documents, in which some contain the word notebook written
separated, e.g. "some dummy words note book other dummy words". And I'd
like that when I search notebook, these documents could be found and I'd
like to do it for a general case, like trying to search the words joining
the word before or after.
How could I do that? Is there an analyzer which tokenize like that?
Thank you
Alex

Alex, to fix your compile problem, check to see if you have lucene 2.9 core
in your classpath.
The analyzers contrib depends upon this.
If you fix it so you can change TOKEN_SEPARATOR, maybe you want to submit a
patch? :)

To use ShingleFilter, I'd like to change its TOKEN_SEPARATOR, but it's
final. Furthermore, I tryed to compile its source code but the compiler
isn't finding some methods like addAtribute.
Does someone know how could I do that?

Yes, but I'd like to do it in a generic way. I wouldn't like to search if my
query contains the word "notebook".
Thank you

Hi,
Simplest way is to add one condition (assuming field is f1):
f1:notebook f1:"note book"
which means (notebook OR "note book"), 2nd condition is phrase
search.
Best regards, Lisheng
