Hi there,

I need to write a multi-criterias search engine including full text search.

For example : show me every message containing "A" or "B" between date "X" and date "Y".

I just want to index the messages content, but no other data.
Is it possible to use hibernate search in this case ? Or do I have to implement Lucene Filters and index everything ?

Thanks for any clue.

Hi,

Hibernate Search seem to be a good fit for your problem. Using the annotations @Field and @IndexedEmbedded you can control what gets indexed and how. Whether or not you will need filters depends on your use case. When using date range searches filters are often a good solution. This has nothing to do with "indexing everything" though. Implementing and using Filters is very easy in Hibernate Search.

I recommend you start with the online documentation and read through the examples there.

Hi Hardy, thank you for responding.

I've read the online documentation, but I didn't see any example mixing filters/criterias and full text search.
The Filter chapter is about implementing Lucene filters.

So I may misunderstand, but for me Lucene must have metadata to apply these filters, so data is indexed.
Am I wrong ?

Furthermore, do you know if it's possible to use OR clauses ?

In case you are planning to mix Hibernate Criteria queries and Lucene queries - that is not supported and would in fact be very inefficient. We recommend you are indexing all the data you need for performing your searches against the Lucene index.
And yes, you can have boolean operators in Lucene queries (AND, OR, NOT). Make sure to check the Lucene query syntax.

Ok thanks :)

okay this is nice...
