Sort a Multivalue field

[Jörg Agatz <jo...@googlemail.com>]

Hallo Friends,

I have a Problem...

my Search engins Server runs since a lot of weeks...
Now i gett new XML, and one of the fields ar Multivalue,,

Ok, i change the Schema.xml, set it to Multivalue and it works :-) no Error
by the Indexing.. Now i go to the Gui, and will sort this Field, and BAM, i
cant sort.

"it is impossible to sort a Tokenized field"

Than i think, ok, i doo it in a CopyField and sort the CopyField..
and voila, i dont get an error, but hie dosent sort realy, i get an output,
but no change by "desc" ore "asc"

What can i do to sort this Field.. i thinkt, when i soert this field (only
Numbers) the file comes multible in the output, like this...


xml:
field aaa>1122</aaa>
field aaa>2211</aaa>
field aaa>3322</aaa>

sort field aaa

*1122*
1134
1145
*2211*
2233
3355
3311
3312
*3322*
...
...
...

i hope you have a idea, i am at the end with my ideas

Unfortunately you can't sort on a multi-valued field. In order to sort on a
field it must be indexed but not multi-valued.

Have a look at the FieldOptions wiki page for a good description of what
values to set for different use cases:
