hello,
thx for u reply, i used the explain method and i understand now why some
documents are returned.
I am using the same Analyzer for indexing and searching.
I tried to only add the content of the page where that expression can be
found (instead of the whole document) and then the search works.
Do i have to split my pdf text into more field? Or what could be the
problem?

Try using the explain() method to see why the documents that were

If I am understanding correctly, you are saying that Luke shows that
those words aren't actually in your index? Can you elaborate on what
your analysis process is? Are you searching using the same Analyzer
as you are indexing with? I would try to isolate the problem down to
some unit tests, if possible.
Cheers,
Grant

Hello,
My application is working with PDF files so i use lucene with PdfBox
to create a little search engine. I am new to lucene.
All seemed to work fine but after some tests I saw that some
expressions like "stock option" where never found (or returns the
wrong documents) even if it exist in my PDF files. I searched in the
mail archive and found that I have to use the "French Analyser" but
that didn't work too.
I found that there is a tool named Luke to check the lucene index. I
could see that the original text contains those words but nothing in
the tokenizer.
Anybody who can help or can explain where I can start to look ?
thanks
