Re: Nested Queries

Hi Kapil, I am not sure exactly what you asking, could you give an example of the correct response? Also, are you truly using numbers or are they just substitutes for text? And are they part of a bigger problem requiring Lucene? If it is just numbers, maybe a DB might be the better way

RV: nested queries

Hi all, We are using Lucene to search business objects with simple queries, but now we need advanced searchs. For example, we have a user object which has as indexed fields the type of the object, its id and its role, and an account object which has as indexed fields the type, its id and the id
