Hi Veit.
Thanks for answering.
I figure it out. In my class Index's constructor I created the
StandardAnalyzer, but when the constructor ends its work this variable is
lost, then in some point that I need the analylzer it's not null, however
it's pointing to nowhere.
I moved the analyzer to the scope of class and then everything worked fine.
I'd like to take the advantage of this email to ask two other things:
1. When I get my documents in the Hits object, how do I know how much
similar they are? Using score() method from Hits? Because I passed the same
text that I indexed before and the score of the document was 0.58. I thought
it was strange because I passed the same text used to index it. I'm asking
this because I want to return only documents which are at least 75% similar.
2. I'm indexing portuguese documents. Does it matter? If so, how can I tell
CLucene that I'm indexing/searching portuguese documents.
Thanks in advance for your support.
