The Query speed is extremely fast, It provides response only in a few milli seconds even for a complex data query. It enables you to have catalog searching, and type ahead search in your application. Suitable for data, that needs frequent searching and fetching.

"We use solr to index our institutional repository data "

"Excellent Document DB + Search software"

Kommentare: Great, better than sharepoint search. Customizable, extensibiliy with load balancers are great, Clustering, Document sharding are great and wonderful features. Overall, this is a great product .

Vorteile: Delta query, Quick retrieval, Faster indexing, Schema definitions, Synonyms the features are endless. it almost behaves as a Database. Can integrate with any database i.e any data source. Document sharding and clustering are excellent features.

Nachteile: I doubt that the product will extend its life span as the cloud can retrieve terabytes of data in a minute. What is missing is a single grid widget or tool that apache solr can provide that can search and display like 6 to 10 million records. A need for an administrator console to retrieve information in a columnar format that can be queried is missing. Eg: Datagrid, JQGrid or a datatable like inbuild javascript library based grids.
