Using analyzer while constructing Lucene queries

Hi, For proper results during searches, the recommendation is to use same analyzer for indexing and querying. We can achieve this by passing the same analyzer, which was used for indexing, to QueryParser to construct Lucene query and use this query while searching the index. The question is -

Re: ParalleReader and synchronization between indexes

Thanks Yonik. So, if rebuilding the second index is not an option due to large no of documents, then ParallelReader will not work :-( And I believe there is no other way than parallelReader to search across multiple indexes that contain related data. Is there any other alternative? I think, Multi

Hi Guys, Any comments on this? I was looking into Lucene archive and came across this thread what asks the same question. http://www.gossamer-threads.com/lists/lucene/java-user/50477?search_string=parallelreader;#50477 Any pointers will be helpful. Regards, Rajesh --- Rajesh parab <[EM

Re: Lucene index on relational data

Hi Mathieu, I can definitely store the foreign key inside the dynamic index. However if I understand correctly, for ParallelReader to work properly, doc ids for all documents in both primary and secondary (dynamic) index should be in same order. How can we achieve it if there are frequest changes

Lucene index on relational data

Hi, We are using Lucene 2.0 to index data stored inside relational database. Like any relational database, our database has quite a few one-to-one and one-to-many relationships. For example, let’s say an Object A has one-to-many relationship with Object X and Object Y. As we need to de-normalize r

Lucene 2.3.0 and NFS

Hi, We are currently using Lucene 2.0 for full-text searches within our enterprise application, which can be deployed in clustered environment. We generate Lucene index for data stored inside relational database. As Lucene 2.0 did not have solid NFS support and as we wanted Lucene based searches

Re: Clustered Indexing on common network filesystem

One more alternative, though I am not sure if anyone is using it. Apache Compass has added a plug-in to allow storing Lucene index files inside the database. This should work in clustered environment as all nodes will share the same database instance. I am not sure the impact it will have on perf

Modelling relational data in Lucene Index?
