Change StandardAnalyzer Lucene

I'm trying to search documents by title with StandardAnalyzer of lucene 4.10.3. I read the quotes from a file and the I add the double quotation marks for constructing the query with this:

Query query = parser.parse("\""+doc.get("title")+"\"");

The problem is that when it reads the quote PHILIPPINES SAYS DEBT PACT "BETTER THAN MEXICO'S lucene returns this error

Cannot parse '"PHILIPPINES SAYS DEBT PACT "BETTER THAN MEXICO'S"': Lexical error at line 1, column 52.  Encountered: <EOF> after : ""

How can I solve it?

Thanks!

Solution

  • The problem is that the quote in the text you are searching for needs to be escaped. You can escape text to be searched using QueryParser.escape:

    Query query = parser.parse("\"" + QueryParser.escape(doc.get("title")) + "\"");
