Jacek Plebanek updated SOLR-3799:
---------------------------------
Description:
Following discussion on [email protected]

i would like to introduce the idea of Federated Search in Solr.
It would be nice to have support for real Federated Search in Solr - very
helpfull for people who would like to include some external search results in
their Solr-based system.
By Federated Search i mean searching across not only distributed Solr instances
(existing DistributedSearch in Solr) but also other kind of external search
services.
Typical federated search process includes:
- collection selection step
- results merging
- adapters for external collections connection
- collections representations (used in collection selection and/or result
merging)
I'm thinking about creating full solution with basic example implementation of
each module.
Things to do that comes to my mind are:
1. federated request support in SearchHandler: the place where everything is
tight up.
2. CollectionSelectionComponent: which should be independent, so one can use it
separately.
3. federated search support in QueryComponent: with no hard-coded agorithms if
it's possible.
4. Results merging rules module: as pluggable part of QueryComponent or as
separate MergingComponent.
5. Adapter (connector) to external collection: interface and example
implementation.
6. Collections representation: interface and default implementation: Used to
store informations about indexes/collections.
The typical use case would look like this:
- user sends search request
- Solr decides to which indexes delegate the request (collection selection):
for example by comparing user's query with collection representations.
- Solr decides how many and which documents get from each collection (merge
rules): for example by using previous step results.
- Solr sends user's query to collections (Solr instances and/or external
collections through dedicated adapters)
- Solr merges and retuns the results.
Design requirements:
- lightweight implementation
- designed as Solr feature, not as something on top of Solr or as Solr extension
- easy to use and customize out of the box
- allow for extension/reimplementation by users
Any suggestions/discussions welcome!
