Lucene: exception - Query parser encountered <EOF> after “some word”

[stroncod]

I got a problem when trying to read a dataset with special characters and trying to get the concept vector.
This is easily solve by adding the escape function in the Vectorizer class

public ConceptVector vectorize(String text) throws ParseException, IOException {
        Query query = queryParser.parse(**QueryParser.escape(text)**);
        TopDocs td = searcher.search(query, conceptCount);
        return new ConceptVector(td, indexReader);
    }

Great implementation by the way! Thanks

Thanks for using ESA, and even more for your feedback!

text is expected to be plain text, without control characters (such as quotes to combine multiple words into a single token), so I think your solution is correct.
