This has been fixed in r82976.

This patch includes both the previous patches but, instead of adding a text field that allows to ignore any pair of "class:property", it just adds an "Ignore attachments" checkbox just under the "All text" field in the search page. The checkbox is checked by default, meaning that the content of the attachment is not included in the search. Searching in the attachment is also turned off from the default search (the one in the top-right corner).

Please review and comment.

I thought about a few solutions to this problem. In the search page we could:
  1) Add an "Attachment" field just after the "All text" and "Title" fields in the search page, and change the "All text" field to either search only in the messages or messages and title. This is more complicated but more flexible.
  2) Have a single "Text" field with 3 check-boxes: "Messages", "Title", "Attachments". This won't allow searching different things in different places but it's easier to use.
  3) Just add a "search in attachments" check-box and change the "All text" search to search only in messages and titles.

The default search should just ignore files by default.

This patch adds the ability to ignore "class:property" pairs to Roundup
(templating.py).

Searching for terms using the top-right searchbox or the "All text" input in the
search page often includes spurious issues where the match is restricted to
attached files.

This patch offers an interface to allow excluding
"class:property,class1:property1" pairs from the results set. It can be used to,
e.g., find issues with 'atheos' anywhere except:
  in attached files ('file:content', the default);
  in issue titles ('issue:title');
  in attached files or in issue titles ('file:content,issue:title').
