[Sanne Grinovero (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-119?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=33403#action_33403 ] 

Sanne Grinovero commented on HSEARCH-119:
-----------------------------------------

this is interesting, are there suggestions for the API?

I was thinkig about something like 

FullTextQuery similar( type.class, Serializable id, String[] fields );

or

FullTextQuery similar( Object indexedEntityInstance, String[] fields );

> Scenario:
> Your bookstore application needs a function as follow:
> When a user see a list of books, there is a similar books button for each book. If user clicks this button of one book item, the similar books will be listed. The similarity is evaluated by all terms in summary of the book and similarity score is dirived from Lucene search similarity package which uses term frequency vectors in calculation. It will compare the target in all corresponding documents in the index and return the hits in order. 
> Note: this funtion is not same as fuzzy query which still needs a definite query condition. In the contrast, similarity search only needs one or several fields (of object/document)to be specified and the rest will be automatically caculated by lucene.
> A QBE-like API should be used to make such query. You can specify the fields in such query.
> Please see discussion about this topic in the forum: http://forum.hibernate.org/viewtopic.php?t=979692
