Now, each attachment is indexed in its own Lucene document, and the content of the owner XWikiDocument of that attachment isn't included in the indexed text. Another problem is that the filename isn't split on dots, so jpg won't match. Lucene doesn't support wildcards at the start of a search term, so you can't search for *.jpg either. So, your only choice is to patch the Lucene plugin to either: - include the list of attachments in the LDocument corresponding to an XDocument, but this means that the search will return not the attachment, but the owner document - include the owner XDocument content in a field of the LDocument corresponding to the attachment, and also index the MIME type of the attachment in a field so that you can search for: type:attachment AND mime:"image/jpg" AND doccontent:"foo" -- Sergiu Dumitriu http://purl.org/net/sergiu/
