The new default configuration takes care about compatibility so that if you have existing relations in Jena graph you will still be able to transparently access them.
Partially missing fulltext index for the title field
Old versions of Nuxeo DM might have document before the introduction of the "fulltext_title" index. This is visible on the 5.5 release thanks to the new search suggestion widget that might be missing some suggestions on old documents.
UPDATE fulltext SET simpletext_title = NX_TO_TSVECTOR("dublincore"."title") FROM dublincore WHERE "fulltext"."id" = "dublincore"."id";
PostgreSQL fulltext phrase search
In Nuxeo 5.5 for PostgreSQL we've added a better way to store fulltext information that enables the use of phrase search. If you want to use phrase search, you should follow the upgrade notes of NXP-5689. If you do this fulltext upgrade, you may want to check the (unsupported for now) nuxeo-reindex-fulltext plugin to get more accurate phrase search results.
