Question

I have been searching this a lot, but everything I do, does not seem to work, I tried,

cat: wolf; category desc
cat: wolf; sort category desc
$query->setQuery("cat: wolf")->sort("category desc");

I cannot sort the results, I have no idea what to do.

Answer 1

Sorting doesn’t work well on multivalued and tokenized fields.

Documentation

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 (or KeywordTokenizer with lowercase filters and ascii filters applied) and copy the category field into the new field.

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

<copyField source="category" dest="category_sort" />
