Problem indexing isbn
Hey guys.
I have searched around abit, and I havent really found a solution to my
problem, so I'm gonna try here.
I am trying to index an ISBN number using a StandardAnalyzer, but i get
absolutely no hits when I try to search on that ISBN number. Every other
search I do works perfectly, so I know that everything is set up
correctly.
I have tried to look at the code for the StandardTokenizer and as far as
I can see, it should be able to index ISBN's.
I feel pretty sure this is just another case of "stupid developer", so
if anyone have any pointers or hints, they would be appriciated.
Best regards,
Thomas Skovsende

ok about the "-", but i still think that the keyword analyzer is the
best option in case the isbn is in a separate field.
This point in the lucene faq cover the most common causes of this error.

Jokin:
I don't agree , StandardAnalyser doesn't break xx-xx-xx , but keeps it
as is.
Try Luke to have a look ( rhyming unintentional :) , tab Plugin shows that.
)
Thomas:
If ISBN is a separate Lucene field ( you don't concat database fields for
searching ) , are you sure it is either default or you explicitly use
field name when searching.

standardAnalyzer will break the isbn at the "-" characters. I think
the best option in this case is to use a keyword analizer that will
index the field without analyzing it.
