Re: [infinispan-dev] Querying Infinispan -- Help Needed
Hiya Vinoth,
I just ran my tests locally, and they seem to be working fine.
My class in my test looks like this: -
@ProvidedId(bridge = @FieldBridge(impl = StringBridge.class))
@Indexed(index = "person")
public class Person implements Serializable {
@Field(store = Store.YES)
private String name;
@Field(store = Store.YES)
private String blurb;
@Field(store = Store.YES, index = Index.UN_TOKENIZED)
private int age;
Perhaps if you have a look at the differences between our annotations
and have a play around you'll be able to find out what the issue is. I
used exactly the same annotations as you did

Hi,
I have a problem in getting through the querying feature of
infinispan. I am using the technical preview listed in this wiki
page with the help of the sample code provided in the same page.
I used the following properties for the second argument in
QueryHelper Constructor.
#hibernate.properties
hibernate.search.default.directory_provider
org.hibernate.search.store.FSDirectoryProvider
hibernate.search.default.indexBase=/usr/vin/lucene/indexes
This is my class for Hibernate Search
@ProvidedId
@Indexed
public class Item {
@Field
private String name;
@Field
private String description;
...// getters and setters
}
I have included the @ProvidedId since QueryHelper instantiation
validates the classes based on this annotation.
Note :: QueryHelper.validateClasses() -- This is to check that both
the @ProvidedId is present and the the @DocumentId is not present.
This is because don't want both of these 2 annotations used at the
same time.
When I used the @Indexed annotation for the above class, it throws
an exception while instantiating the QueryHelper.

<Exception Snippet>
When I removed that @Indexed annotation, QueryHelper got
instantiated but it throwed some exception when it hits
CacheQuery.getBasicQuery() method, where it forms lucene query
string with the help of QueryParser.
org.hibernate.HibernateException: There are no mapped entities.
Don't forget to add @Indexed to at least one class.
Yes, Hibernate Search will throw an exception if you don't specify if
any of your classes are Entities. If there aren't any entities then it
doesn't know what to index :-).
Please let me know if I missed anything here.
Thanks in advance,
Vinoth
