Search, stores and their purposes

calle — Wed, 08 Oct 2008 13:47:14 GMT

HiI am implementing a service that searches in old versions of content.From what I have understood reading about the SearchService I should change the StoreRef being used in the SearchService.query(…) call. I use Alfresco 2.2 e. I have found several threads about this but none explains the problem f

I have made some progress…
First, I believe that the Store to search in is workspace://lightWeightVersionStore. If I search for all objects (by query PATH:"/*") then I get the expected number of hits back. What I do not understand is what I am getting back I can see it is of type {http://www.alfresco.org/model/versionstore/1.0}versionHistory and I get a bunch of properties for each node for example the node id of the versioned node in workspace://SpacesStore (VersionModel.PROP_QNAME_VERSIONED_NODE_ID).

Now I am able to get all the nodes in the lightWeightVersionStore and get a reference to the current version node. What I am still not able to do is search in the lightWeightVersionStore for old properties or in content without manually searching in the list of returned versionHistory objects. What I wonder is if only the properties in the versionstore model are being indexed for old versions which would make it impossible to search for properties or content in the old version.

Hi,

I think you're right on all points. The lightweightVersionStore storage model is very specific. As each native property is mapped to a node in this store, a document in the workspace://SpacesStore will be mapped to several nodes here, and a composite Lucene search will not work because criteria would have to match on different nodes… Worse, the content is not indexed at all in the lightweightVersionStore !
Performing complex searches in this store will not be easy :cry:
