All right! I've done this already. I thing you dont understand my question. What I want to do is to query my indexes using something like "filetype:pdf". The version 0.8 already have this feature. But I'm using the version 0.7.2 and I want to add this feature mannually. But I dont know where I have to edit. Do you know?

Hi, To allow more formats to be indexed you need to modify nutch-site.xml and update/add plugin.includes property (see nutch-default.xml for default settings). The following is what I have in nutch-site.xml: <property> <name>plugin.includes</name> <value>nutch-extensionpoints|protocol-http|urlfilter-regex|parse-(text|rtf|html|js|msword|mspowerpoint|msexcel|pdf|zip|rss)|index-(basic|more)|query-(basic|site|url|more)|summary-basic|scoring-opic</value> </property> [parse-*] is used to parse various formats, [query-more] allows you to use [type:] filter in nutch queries.
