In
my opinion, one of the problems of creating an "opac-any" index in
zebra is that many of the fields and subfileds in MARC are not meant
to be shown to the public, and indexing them confuses things. If they
don't appear in the opac, yet do appear in the search results, the
patron is left wondering why.
Hello Linda
I have given a bad name to my "opac-any". I should have said
"opac-just-the-fields-we-want-to-index"...
In the current record.abs, the index "any" is defined as "all any". So,
if I understand well, all the fields indexed in other indexes (title,
author, subject, notes,
Local-number,Identifier-standard,Country-heading, items, etc etc)
At least this is the way it works in Unimarc. Maybe not in Marc21 ?
So, for example, in my unimarc catalogue, if I search for "fre" in the
opac, I've got 342825 results, because it is
the code for french language in 101a field, index in "ln". gasp.
idem if I search for "lc" or "rameau" (equivalent to LCSH in France),
or "texte"
And with fuzzy or autotruncate activated, it is, well..., very very
annoying.
So my idea was
- to keep the "all any", because it could be usefull somewhere in Koha
perl code or templates
- to create a more specific index, matching only important field, but
in any event NOT matching coded fields and some boring notes...
- to use this index in opac simple search (and maybe in staff interface
simple search but this could be discussed...)
There
is also the problem that Koha doesn't have a way of dealing with
indicators, such as the "traced" or "untraced" in the 490, for
example. For a record that has minimal cataloging it may not be a
problem, but with a fully cataloged record, it would pull up a lot of
false results. But that is just my 2 cents worth - admittedly not worth
much, inflation considered.
Completely agree with you for the indicators. I think it is less
important in unimarc, but that would be very useful if Zebra could
manage them :(
Regards,
Mathieu
