One of the problems that I have with Evergreen searching, which I've
complained about before is the way that the system will search fields that
are not displayed in the search results screen to the average user.
My favourite example is an author search for "Fiander" in PINES. There are
some books in the library field that might appear, but you also see some
british videos that appear, and there's NO indication in the public display
why they matched a search for Fiander, until you look at the MARC display
and discover that the actor Lewis Fiander (no relation) appears in the cast
list, which is not displayed to the public.
One of the first rules of cataloguing is that access points (ie search
fields) MUST be supported by the record somehow.

Patrick,
The 700 field in a MARC record is an author field. It is used when there
are either multiple authors for the item (since the 1xx fields are not
repeatable) or when the person responsible for the work is an editor. So
we do want an author search to include the 700 field.

Subject: [OPEN-ILS-DEV] Introduction and Question
Greetings!
This is my first post so first a word or two about my background. I am
currently a co-editor for the OpenDocument Format standard in OASIS and
its project editor in ISO (ISO 26300). I am also chair of the US
committee that is the mirror commitee of SC 34, which is currently
considering OpenXML (DIS 29500). When I am not involved in either of
those projects, I am the convener of SC 34/WG 3, Topic Maps, as well as
a co-editor of various parts of that standard. I am an independent
consultant on standards (primarily markup and semantic integration) and
related technologies.
My question: Where are the search and relevance sections of the
Evergreen code?
I ask because I was posting an ILL for "Computers and Intractibility: A
Guide to the Theory of NP-completeness" to my local library and in an
effort to be helpful, I did a keyword search in Pines for
np-completeness (note the lack of quotes) thinking that is a fairly
unique term. Try it with Pines. The results are rather amusing and quite
definitely not relevant.
I performed the same keyword search with "np-completeness" and got no
hits. (I would have expected to have the same results with the first
search.)
That made me curious so I tried searching for author, Garey, thinking it
is a fairly unusual spelling so I would not get too many hits.
Ok, I get some "garey" authors in the first 10 "hits" but also:
Found objects a style and source book
Ruggiero, Joseph.
Slipcover chic : designing and sewing elegant slipcovers at home
Revland, Catherine.
As "hits" 9 and 10.
Perfectly fine books I am sure but not what I would be looking for when
searching for author = garey.
Anyway, since searching is one of my interests (topic maps and their
construction) I was puzzled by the anomalous result.
Looking at the MARC record for the Revland, Catherine "hit" it appears
that author = garey request is searching the 100 field *and* the 700
field, which for this item includes:
700 aBall, Michell, ill.
700 aGarey, Carol Cooper
Which would be understandable if I had asked for a "keyword" search. Not
so understandable with a author search.
Well, I suppose I have two questions in addition to my first one, ;-) .
2. Where is the "relevance" code in particular since it was the source
of the seemingly odd results on np-completeness.
3. Shouldn't author searches default to the MARC 100 field? (With
keyword taking in 700 entries, etc.)
Hope everyone is having a great day!
Patrick
