How do you do this?, ie to get a list of files/objects that contain the search term, laid out in a way that the external user would recognise.
I don't mean the 'find' tag in the manage screens, by the way...
The find management screen does give helpful hints. If you want to implement this kind of searching, you'll have to use the same techniques. These are however largely undocumented. The file lib/python/OFS/findResult.dtml should give you a lot of hints on how to implement a search command. It comes down to calling PrincipiaFind on a Folder with the right arguments: obj, obj_ids, obj_metatypes, obj_searchterm, obj_expr, obj_mtime, obj_mspec, obj_permission, obj_roles, search_sub, REQUEST, result, pre where * obj -- base folder to start at * obj_ids -- (optional) list of object ID's to search * obj_metatypes -- (optional) list of meta types to search for (if the string 'all' is in this list, all objects, whatever their meta type will be included in the results). * obj_searchterm -- (optional) literal text to search for in the *source* of DTML Documents and DTML Methods. * obj_expr -- (optional) DTML expression (as would be used in the expr attribute of for example the var tag). If this expression returns true within the context of an object, the object is included in the search results. You could use this for testing on certain properties, like 'foo=bar'. * obj_mtime -- (optional) DateTime object or string that can be converted to a DateTime object, specifying a modification time to compare objects against. Will on default return objects that have been modified since obj_mtime. * obj_mspec -- (optional) When used with obj_mspec, and set to '<', PrincipiaFind will only return objects which have been last modified before the date and time specified by obj_mtime. * obj_permission -- (optional) To be used together with obj_roles. Check if the roles specified by obj_roles have the obj_permission permission. Only these objects are included in the results. * obj_roles -- (optional) List of roles to check for obj_permission access. See obj_permission. * search_sub -- (optional) if true, search subobjects recursively. * REQUEST -- (optional) REQUEST object, used to make sure that AUTHENTICATED_USER is available for obj_expr expressions. * result -- a list of objects to be included in the returned results. Used by the PrincipiaFind method when recursively searching subobjects. Generally of no use to us humble DTML programmers. * pre -- prefix the IDs in the returned result list with pre and a slash. So, when called with pre='foo', and bar is the only object found, PrincipiaFind will return the list of tuples: [('foo/bar', foo)]. This argument is used when recursively searching subobjects, where pre is the relative URL of the object searched. Generally of no use to us humble DTML programmers. The method returns a list of tuples, where the first element of every tuple is the relative URL of the object found (relative to the starting point), and the second element is the object itself. -- M.J.
