Hi, so this is only available in 1.5?
I tried in 1.4 and got :
org.apache.solr.common.SolrException: Error loading class
'solr.CollationKeyFilterFactory'
Is there a way to do this in 1.4?
The link Shalin sent is a 1.5 link I think.
thanks

Hello, as Shalin said, you might want to try
CollationKeyFilterFactory.
Below is an example (using the multilingual root locale), where the
spaces will sort after the letters and numbers as you mentioned, but
it will still not be case-sensitive. This is because strength is
'secondary'.
But are you really sure you want the spaces sorted after the letters
and numbers? Or instead do you just want them ignored for sorting? If
this is the case, then try 'primary', so that spaces, punctuation,
accents and things like that in addition to case are ignored in the
sort: for example "Test-1234" and " test1234" sort the same with
primary, but not with secondary (the one with leading spaces will sort
last)
If all else fails, you can write custom rules for it too, as Shalin
mentioned.
<fieldType name="collatedROOT" class="solr.TextField">
<analyzer>
<tokenizer class="solr.KeywordTokenizerFactory"/>
<filter class="solr.CollationKeyFilterFactory"
language=""
strength="secondary"
/>
</analyzer>
</fieldType>

update, I tried changing to datatype string, and it sorts the

better, but the other sorts are not as good.
Is there a way to control sorting for special chars, for example,
I want
blanks to sort after letters and numbers.
In the general case, CollationKeyFilterFactory will do the trick.
You could
create a custom rule set which sorts spaces after letters and
numbers. See
http://wiki.apache.org/solr/UnicodeCollation
using alphaOnlySort - sorts nicely for alpha, but numbers dont work
string - sorts nicely for numbers and letters, but special chars
like
blanks show up first in the list
alphaOnlySort has a PatternReplaceFilterFactory which removes all
characters
except a-z. This is the reason behind those wierd results. You
could try
removing that filter and see if thats what you need.
