ok, i read that in javadoc of lucene... in dont understand what
Field.Text(String,Reader,boolean) does... if i set boolean to true,
what is the stortermvector??
Term vectors is additional index storage allowing you to find out how
many of each term occurred in a field. For your purposes, you don't
need to use that feature.
You have some options... change to using a stored field by reading
the file contents into a String and using Field.Text(String,
String) instead. Or, when rendering the results, go directly to
the file pointed to by doc.get("filename") and read its contents
then. There are pros/cons to both of these approaches.
ok, i started to try this... but i also try to index pdf-files.. so
i get an InputStream from pdftotext. if i try to convert that to a
String it takes really long time,
and we have a lot of data to index....
i tried different ways to get that done:
1.
String ret = "";
InputStream is=null;
String[] cmd = {"/usr/bin/pdftotext", "test.pdf", "-"};
byte[] buffer = new byte[80];
child = Runtime.getRuntime().exec(cmd);
is = child.getInputStream();
BufferedInputStream bis = new BufferedInputStream(is,80);
while(next != -1){
++t;
next = bis.read(buffer,bis.pos, 80);
String input = new String(buffer,0,next);
ret += input;
}
not really that way, but conceptual (in real it compiles :-) )
2.
String ret = "";
InputStream is=null;
String[] cmd = {"/usr/bin/pdftotext", "test.pdf", "-"};
byte[] buffer = new byte[80];
child = Runtime.getRuntime().exec(cmd);
is = child.getInputStream();
while(next != -1){
++t;
next = is.read();
ret += String(next);
}
but those versions are both really slow... it takes me more than 20
minutes (minimum) to get a pdf file of size 900 k...
is there a way to get that faster???
You should consider using PDFBox for reading PDF files.
