Hi Ganesh, Thank you for quick response. Most of these documents will have more than 10 fields. In some cases there is also a foreign key relationship. Will consider JSON. Also need to consider performance factor.

This should not be tedious, how big your document is? One suggestion is to convert your Java object to JSON and store it in Lucene. You need to retrieve one field and you can easily convert back to object.

Basically, at the application startup I run a select query on entities ( there are 5 of them as of now and may increase in future) and then create an index for each of these entities (5) i.e. five different indexes as of now(cannot have a common index. Need separation of entity data). Ideally I would have liked to store only primary key field, but I need rest of the fields upon fetch. > I use this index(basically only the primary key field) to prevent users from creating duplicate entities or suggest them like a Did you mean(Google) ? feature . For this purpose, I’m using SpellChecker module to suggest entities or identify duplicates. Since, Spell checker only returns a String array, I again have to run a select separate search on the index(QueryParser search) or run select on the DB to fetch the entire object. Furthermore converting the Lucene Documents to Java object and vice- versa is a tedious task. Is there any API or library that can simplify this task ? I have heard of Compass API, but not sure if it is still recommended. Any examples of the same or APIs will be appreciated. Thank you !!! > > > Thank you and Regards, > Santosh
