I´ve read WHATSNEW and there are no hints to range_look or whatsoever.
Maybe the english text is too difficult for me?
I _must_ be strong of stomach! I _must_ be strong of head to understand
all english text and and your fine codes. I make a survival training
every day (eating iron and beating my head with wooden beam). ;-))

I´ve copy and paste your above codes and i get
------------snipp---------
Sorry, there was an error in processing this form action. Please report the error or try again later. (Can't use an undefined value as an ARRAY reference at
/home/mvend4/lib/Vend/TextSearch.pm line 142. )
------------snipp---------
If i delete <INPUT TYPE=hidden NAME=mv_range_look VALUE=erjahr>, it
can´t find ..."2000 | 2000 | Kind".
I´ve updated minivend from 4.02 to 4.03 today. I´m sure, your codes
works well for you. I make my survival training once more and read your
codes get_limit in Search.pm and TextSearch.pm at the line 142.
Hmmmm....i look into your codes like a cow with no idea how to play
piano. ;-)
Another results differences between MV4.03 and MV3.14-3.
1) Searching for "Kind" with no mv_range_look
MV 3.14-3 MV 4.03
289 items 17 items
2) Searching for "Kind" and publisher is "Juventa" with no mv_range_look
MV 3.14-3 MV 4.03
40 items 2 items
3) Searching for "Kind" and author is "a" with no mv_range_look
MV 3.14-3 MV 4.03
253 items blank page (no message like
"Bad Search Specification
The search could not be done. The problem was:",
but value mv_match_count is "-1")
4) Searching for "Kind", author is "Hans", Publisher is "Juventa",
the part of code is "37799", with no mv_range_look
MV 3.14-3 MV 4.03
6 items The same as (3).
5) The same as (4), but without "<INPUT TYPE=hidden NAME=mv_coordinate VALUE=yes>"
MV 3.14-3 MV 4.03
6 items 6 items
6) Searching for "Kind", Publisher is "Juventa" *and* *with* range_look
for the years "1994" and "1996"
MV 3.14-3 MV 4.03
14 items 14 items
Very strange! Check with "Kind", publisher "Juventa" and min/max with
"2000" results
MV 3.14-3 MV 4.03
2 items 2 items
Well duh! I get it! This is what i want! It works with the same old
codes as MV 3.14 without mv_coordinate. Is strange!

This would be very very fine!
