: I think you can use something like "q=hello world -books". Should do.
or just "q=-books" ... finds all docs that do not have books (in the default search field) : > so solr returns all documents, that don't have "books" somewhere in them? "somewhere" is kinda vague ... if you mean "don't have the word 'books' in any field" then not unless you use copyField to create a "catchall" field you can query against containing all the text. -Hoss
