Hello,

I don't know if it's possible, I make a search on 2 classes (for example Class1 and Class2), so I have :


Then, I want to made a


I have 2 records in Class1 :
field=a
field=c

and 2 records in Class2 :
field=b
field=d

and I want the result is :
field=a (Class1)
field=b (Class2)
field=c (Class1)
field=d (Class2)

I see in Lucene javadoc that we could Sort by 2 fields, but it's like in SQL, the first field is more important that the second.

Is it possible to do that ?

Thank you.

I am not sure if I understand your use case completely, but I think it should be possible.

If I understand correctly you have two classes Class1 and Class2 (and hence two indices /usr/lucene/indexes/Class1 and /usr/lucene/indexes/Class2). Both classes have a property called 'field'.

if this is correct

should do what you want. HSearch opens a MultiReader under the hood towards each of the indices and then executes the search against both indices. Provided that the field names match you should get a list of mixed types (Class1 and Class2) from fullTextQuery.list().

I recommend to use Luke http://www.getopt.org/luke/ to inspect your indices. This helps to understand what's happening under the hoods.

Thank you very much ! It works very well with the same field name ;).
