I think you wanted to remove letters, but your pattern removes NON-letters -
that's what the "^" does, negation.
So, try: ="[a-z]".
You can also get rid of the lower case filter and just use "[a-zA-Z]".

Subject: How to sort value that numeric mix alpha
Dear all,
Could anybody suggest me how to sort the field that has numeric mix with
alpha.
In my case I have field name 'product_id' which contain value like
C1,C2,C3,C4,C9,C12,C23,C50
when I try to sort (DESC) it return wrong result something like this
C9,C50,C4,C3,C23,C2,C12,C1
As you see I have 'C' for prefix.
So, In my Schema.xml I have tried this...
<fieldType name="alphaOnlySort" class="solr.TextField"
sortMissingLast="true" omitNorms="true">
<analyzer>
<tokenizer class="solr.KeywordTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory" />
<filter class="solr.TrimFilterFactory" />
<filter class="solr.PatternReplaceFilterFactory"
pattern="([^a-z])" replacement="" replace="all"
/>
</analyzer>
</fieldType>
<field name="pid_sort" type="alphaOnlySort" indexed="true" stored="true" />
<copyField source="product_id" dest="pid_sort"/>
but it didn't work. How to deal with this?
Thank you very much,
Chun.
