</body>
</html>

If I change and sort by path, it works

Here is my query :

{def $params=hash( 'query', $searchtext,
                             'limit',$limit,
                              'sort_by', hash('name', 'asc'),                              
                              'offset',$offset,
                              'subtree_array', array($node.node_id),
                              'class_id',$classid)}       
{def $resultats=fetch( 'ezfind', 'search',$params)}


Thx, Fabien

You can write a comment on that issue. Then developers will know that more people have that problem and maybe they speed up resolving.

Maybe :)

Indeed,

The default field type for the "name" meta data is "text" which cannot be used to sort (it is split in multiple terms which causes the error you see)

However the following recipe will help you:

You can add a schema definition in schema.xml that does a copyfield from "meta_name_t" to "meta_name_s" (of type string) and use the latter for sorting

So in schema.xml add a new field definition in the <fields> section

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

Then add a copyfield construct:

 <copyField source="meta_name_t" dest="meta_name_s"/>

Finally reindex your site (needed with amost all schema changes) and then modify your fetch functions as follows:

{def $params=hash( 'query', $searchtext,
                             'limit',$limit,
                              'sort_by', hash('meta_name_s', 'asc'),                              
                              'offset',$offset,
                              'subtree_array', array($node.node_id),
                              'class_id',$classid)}       
{def $resultats=fetch( 'ezfind', 'search',$params)}

That should be it

PS: from eZfind 2.3 it should not be needed to do this as you can already do for regular attributes: specify different field types for search, sort, facet and filter
