And, then each partition is replicated to a different server in the cluster by using Partition-Replica Cache topology in NCache.

- Lucene Index Replicated: Lucene index is partitioned across all the servers in the cluster.Here are some highlights of Distributed Lucene in this area: - Grow Lucene Index at Runtime you can add more items to the Lucene index at runtime without stopping or rebuilding the entire Lucene index.Lucene index is automatically redistributed to all the servers in the cluster without any interruptions. - Add/Remove Servers from Cluster at Runtime: you can add more servers to NCache cluster at runtime without stopping your application or rebuilding your Lucene index.

Then, results from all those parallel queries are merged before returning to your application. And, this way, your query runs in parallel across multiple servers.

- Parallel Searches: since Lucene index is partitioned, when your application issues a full text search query, Distributed Lucene sends it to all the servers in the cluster.This way, as you add more servers to the cluster, Lucene index is automatically repartitioned and redistributed in an intelligent manner by using NCache Partition-Replica Cache topology. - Lucene Index Partitioned: in order to provide scalability, Lucene index is partitioned across all the servers in the cluster.As a result, Distributed Lucene is also in-memory and therefore very fast. - In-Memory (Fast): Distributed Lucene is built on top of NCache that is an In-Memory Distributed Datastore.- Industry Standard API: by using Lucene in your application, you’re sticking to industry’s most popular full text searching API.ĭistributed Lucene is extreme fast and scalable for the following reasons:.

- No Code Change: you don’t have to make any code changes to your Lucene application in order to use Distributed Lucene.As a result, you get the following benefits from it: Native Lucene APIĭistributed Lucene with NCache provides you a native Lucene API. The results of these distributed searches are then merged before being presented to your application. And, on the back-end, NCache uses the same Lucene.NET to build indexes in a distributed environment and later to conduct full-text searches in a distributed manner. NET application the native Lucene.NET API so you don’t have to change any code in your application. NET Lucene applications in order to use it with NCache. And, due to the native Lucene API, you don’t have to make any code changes to your. This has transformed the stand-alone Lucene into an extremely fast and linearly scalable full-text searching solution for. NET in its native form over its In-Memory Distributed Cache (hence the name Distributed Lucene). Lucene is a stand-alone library that applications embed in order to perform full text searching.
