Solr wrong sort text fields

Question

I have \"text_general\" field in schema.xml

Answer 1

Sorting doesn't work good on multivalued and tokenized fields.
As testata has been defined with text_general field type, it will be tokensized and hence the sort would not work fine.

Sorting can be done on the "score" of the document, or on any multiValued="false" indexed="true" field provided that field is either non-tokenized (ie: has no Analyzer) or uses an Analyzer that only produces a single Term (ie: uses the KeywordTokenizer)

Use string as the field type and copy the title field into the new field.

<field name="testata_sort" type="string" indexed="true" stored="false"/>

<copyField source="testata" dest="testata_sort" />
