Is it possible to perform search on the associations that are part of the document's metadata? I am using an association for cmerson(identical to bpm:assignee) to select the moderator of the document, it is an important part of metadata for my custom content type. I need this search to be possible in the advanced search section, so that every user in the system has the possibility to search on associations that are part of the document. From what I have read, you couldn't perform search on associations in previous versions of Alfresco, is this still an issue? Are there any other good alternatives then, for example, using an extra text property, that would store the values of an associations?
