Subject RE: Lucene refresh index function (incremental indexing).
Date Tue, 25 Nov 2003 04:07:24 GMT
Does it support indexing the contents of pdf files? I have found one project
called PDFBox that can be integrated with Lucene to search inside of the pdf
files. Currently, Lucene can only search for the pdf filename. I tried with
PDFBox and I got the following message when I typed the command: java
org.apache.lucene.demo.IndexHTML -create -index c:\\index .. 

log4j:WARN No appenders could be found for logger (org.pdfbox.pdfparser.PDFParse
r).
log4j:WARN Please initialize the log4j system properly.

Can anyone advise?

To update, try removing the '-create' from the command line.  The demo code
supports incremental updates.  It will re-scan the directory and figure out
which files have changed, what new files have appeared and which previously
existing files have been removed.
