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.

We use solr to index our institutional repository data

It is very flexible and customize-able which makes it very easy to integrate-able with other components in the development stack.

Nachteile:

the query language could be a bit confusing at first. If the collection is large, it often takes a long time to index the data.
