Can you folks tell me more about hibernate search ? I have spent so much time back and forth deciding on how and what should handle my search. I must say, I remember that his was a possibility now early in my development but none in the grails community have mentioned it as an option when I have brought up the search discussion...

How powerful is it? Compared to lucene ? but how come no one have mentioned it in grails... does this come with the normal grails/hibernate distro ? Or is it like a plugin ?

May main reason for considering going for postgres Tsearch is the possibilty to mix fulltext and relational matching... I guess this is not a problem with Hibernate search ? Is there any drawbacks I should know about ? Is it fast, slow.. other things to consider ? Possible to add a dictionary ?

Thanks / Moe

This isn't an extensive reply to your questions:

1) Hibernate Search uses Lucene under the hood, so there is no direct comparison (unless someone can say otherwise) between Hibernate Search and Lucene. Hibernate Search allows you to index and search your Hibernate mapped domain objects. This is currently done via annotations (xml configuration can be plugged in but there is no code as of yet).

2) As far as I know there is a grails plugin for search but I believe it uses Compass search framework which in turns uses Lucene.

3) Hibernate Search has a distribution which you need to place in your application. Please refer to the Hibernate Search documentation for further information on how to get started.

I have been using Hibernate Search for some time now and it's a great library and I would highly recommend it. Please download and build a prototype using Hibernate search to get you going.

Cheers

Ook, thank you... I have looked at compass and Searchable.

You know if "Hibernate search" supports dictionaries (stop words, lexemes etc) ?

"This is currently done via annotations"

Does those look the same across all frameworks? Add to the domain class, right ?

I will go to the documentation and have look now...

Thanks again / Moe

It's been sometime but I did a small blog on using Hibernate Search (via Spring). Hopefully it should give you an basic idea www.amin-mc.blogspot.com
