Subject [jira] [Created] (SOLR-3800) Federated Search: SearchHandler
Date Thu, 06 Sep 2012 12:15:08 GMT
Jacek Plebanek created SOLR-3800:
------------------------------------

             Summary: Federated Search: SearchHandler
                 Key: SOLR-3800
                 URL: https://issues.apache.org/jira/browse/SOLR-3800
             Project: Solr
          Issue Type: Sub-task
          Components: SearchComponents - other
    Affects Versions: 5.0
            Reporter: Jacek Plebanek
             Fix For: 5.0


Federated request support in SearchHandler could look similar to current DistributedSearch
support: design based on STAGE flags and optional requests sending to collections (shards).
The main difference would be in supported stages and in additional request available (request
to collections representation module). Something like:

available stages:
- COLLECTION SELECTION
- PREPARE MERGE RULES
- GET DOCUMENTS

available actions:
- send search requests to shards (to adapters and solr instances)
- send requests to indexes representation

invoked Component's methods:
- federatedProcess()
- handleFederatedResponses()
- handleCollectionRepresentationResponses()


Any suggestions welcome!
