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.

Hi,
I have a requirement to store a Java object with multiple fields into the
Lucene index. 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
