Hi Celso,
just a note, your code makes no sense:
In the constructor of QueryParser you have to give the default field, e.g.
"content" only - With parse() you have to give the query string (which can
contain a field name or not): "computer" or alternatively "content:computer"
(which returns equal results because the default field from the ctor is
content:
QueryParser parser = new QueryParser(Version.LUCENE_30, "content",
analyzer);
Query query = parser.parse("computer");
or:
Query query = parser.parse("content:computer");
