But how could I use content to search the document if I use Field.Text("content", reader). I do not want to save the document content .
Thanks a lot.

1. Field.Text Constructs a Reader-valued Field that is tokenized and indexed, but is not stored in the index verbatim, Thus you can not retrieve the text. You need to use Field.Text("content", String) to be able to read back the content. 2. You can use an open source project called PDFBox which can extract text from a PDF document.

Hi, everyone: I am new to Lucene. There are some questions I want to know why. (1) when I use Field.Text("content", Reader) to index the file content, I can not retrive it when I search. Here is part of code Analyzer analyzer = new StopAnalyzer(); Searcher searcher = new IndexSearcher(indexPath); Query query = QueryParser.parse(queryString, key2, analyzer); Hits hits = searcher.search(query); I can not find the field when I use : hits.doc(i).get("content"). It is null. But I can get all other fields value as the same way. How could I get that? (2) Does Lucene have a way to index pdf content? Which is the best API that can be easy used to change pdf to text? Please response me. Thanks a lot. Haipeng
