Hi Lukas and everybody! Do you know which file in nutch 0.7.2 should I edit to add some field in my index (i.e. file type - PDF, Word or html)?'

Hi, I am not sure if I can give you any useful hint but the follwoing is what once worked for me. Example of query: url:http date:20060801 date: and type: options can be used in combination with url: Filer url:http should select all documents (unless you allowed file, ftp protocols). Plain date ot type filter select onthing if they are used alone. And be sure you don't introduce any space between filter name and its value ([date: 20060801] is not the same as [date:20060801]) Lukas On 8/8/06, Matthew Holt <[EMAIL PROTECTED]> wrote: > Howie, > I inspected my index using Luke and 20060801 shows up several times > in the index.
