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...)

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 :(
