Hi, fellows. That is schema declaration of that property.

  <?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="http://a.com/annotationThread" xmlns:anot="http://a.com/annotationThread">
    <xs:include schemaLocation="base.xsd" />

  <xs:simpleType name="catList">
    <xs:list itemType="xs:string" />
  </xs:simpleType>

    <xs:element name="categories" type="anot:catList"/>
</xs:schema>

What nuxeo file configuration should be done and what query has to be done, so I can use full text search in my defined list?

Something like that:

SELECT * FROM ImageAnnotationThread WHERE ecm:fulltext.annotationThread:categories/* = 'something'
