Hi,

 I’m using lucene on Hebrew MySql tables. I used ngram (1-15 gram sizes) in
my name analyzer and the only thing that doesn’t work for me is when I try
to use ‘%’ in my parsing string (didn’t find any match).

I tried escaping it, using double character (“%%”) but nothing worked.

Thanks,

Gal

Depending on your analyzer, this could well be stripped
from the input. Perhaps try using Luke to examine the
actual values in the index to see if it's there.

And the escape character for Lucene is the backslash.. See:

Special Characters

I tried to use escaping but it didn't work as well (and % is not in the
list).
my field analyzer is ngram (min=1 max=15) and i'm writing the query using
QueryBuilder API rather than string so it's not being parsed.

any ideas?

Thanks,
Gal

And have you used Luke to see exactly what is being indexed, as Erick suggested?

See http://wiki.apache.org/lucene-java/LuceneFAQ#Why_am_I_getting_no_hits_.2BAC8_incorrect_hits.3F.
for other things to check.
