newbie question on querying on multiple attributes
I am using Hibernate as my persistence layer and have recently found
Hibernate Search and Lucene as a possible solution to my full text search.
However, I am a little fuzzy on what exactly needs to be done in my
situation.
In a nutshell, I have a Business object that has multiple of attributes that
needs to be indexed (name, summary, products, services, etc)
I would like to provide functionality in my web app that provides a user a
single text field that would match Businesses against all the identified
attributes.
I am assuming there are more than one option...but what is the best approach
to accomplishing this scenario?
I am assuming that i need to create different terms for each indexed
attribute...correct? If so, do I need to create a BooleanQuery for each
term?
I am sure there is an example out there...but I haven't found one or have
misunderstood what I have seen so far. So if there is a something out
there, could someone direct me to it?
Thanks in advance,
- Doug

Hi,
instead of the ClassBridge you can just annotate all the properties you
want to index with
@Field and build a BooleanQuery out of the input field. Indexing the
properties into
separate document fields is probably more extendable in the future when
you for example
only want to search on a subset of the properties.
I recommend you read through the online documentation of Hibernate Search
and you can also
ask question at the Hibernate Search Forum -
http://forum.hibernate.org/viewforum.php?f=9
which is probably a more appropriate then this mailing list.

Consider the use of the ClassBridge in Hibernate Search. Very useful. It
basically allows you to merge multiple fields of your hibernate entity into
a single lucene field. Once this is done, you can query this single field
from lucene without the need for BooleanQuery.
HTH,
Stéphane
