Search on additional fields added to new CCK type contents

At the moment trip_search uses the title and body fields of a node (it also searches on comments if these are enabled). CCK fields are kept in completely different tables, using specific column names. Consequently, making it possible to search on a CCK field other than title (and whatever ends up in body - it could often be empty) would require a considerable amount of work: in my view the following would be necessary:

• as well as a generic search as at present, it would be necessary to allow trip_search to be called with a particular interface for each CCK type, such that the user could specify that he wanted to search for particular content in a particular field;
• this interface would need to be built by trip_search analysing the various CCK types available in order to determine what fields could be searched on
• the generated SQL would also need to be specific for each CCK type

All this would be a substantial amount of work.
A much easier enhancement would be to include the teaser in the indexed fields that trip_search uses - since CCK allows you to specify what goes in the teaser, it would be a means of including CCK fields, as long as these appeared in the teaser.
I would be interested to know what "mindless" thinks of this.
