Lucene by Example: Specifying Analyzers on a per-field-basis and writing a custom Analyzer/Tokenizer

Sunday, July 6th, 2014

Lucene is my favourite search engine library and the more often I use it in my projects the more features or functionality I find that were unknown to me.

Two of those features I’d like to share in the following tutorial is one the one hand the possibility to specify different analyzers on a per-field basis and on the other hand the API to create a simple character based tokenizer and analyzer within a few steps.

Finally we’re going to create a small index- and search application to test both features in a real scenario.


JPA Persistence and Lucene Indexing combined in Hibernate Search

Sunday, February 5th, 2012

Often we’re writing an application that has to handle entities that – on the one side need to be persisted in a relational database using standards like the Java Persistence API (JPA) and using frameworks like Hibernate ORM or EclipseLink.

On the other side those entities and their fields are often stored in a highspeed indexer like Lucene. From this situation arises a bunch of common problems .. to synchronize both data sources, to handle special data mapped in an entity like an office document and so on..

Hibernate Search makes this all a lot easier for us as we’re hopefully going to see in the following short tutorial…
