Subject Does solr 4.8.1 support these features?
Date Mon, 09 Jun 2014 07:00:48 GMT
My company is actively looking at alternative search engine applications 
to replace our current Endeca application.

I have no experience and knowledge on Solr and Lucene.
Please bear with me, I would like to find out if the following features 
are available on Solr.

1. Aggregate results (rollups).
Eg. Froma list of search result of products (each has field = supplier 
id), can the results be aggregated by supplier id with the original 
results ordering retain.

2. Filter/Navigator, counts.
List out a field's possible values and their counts fromthe indexed data 
and from the return results.
The field's values can be sorted by the values description or by the 
values countsin the return results.

Eg. Field "Business Type" belowwith it's possible values and the count 
for each value(in bracket). Can the field be return in the result with 
it's values sorted either by description or bycounts?
Business Type
Manufacturer (15269)
     Exporter (12493)
     Trading Company (5541)
     Agent (1324)
     Wholesaler (1202)
     Importer (682)
     Buying Office (394)
Distributor (278)
     Other (157)
     Retailer (116)
     Consultant (54)

3. Configureand defined the relevance rankingand matching logic of the 
return result.

4. Defined and configure the thesaurus (1-wayor 2-way), stemming and 
stop words.

5. Multi-language supportfor Simplified Chinese and Spanish.

6. Scalability.
At present, we are indexing 4million recordsand the number is expected 
to increase by more than 10 folds in the near future.

7. Search results debugging. Eg. why record was matchedor why record was 
ranked as such.
