Hi
My intention is to give different terms in a field different boost values.
The queries from a use perspective, will be one fulltext input field.
The following code illustrates this:
Field f1 = new Field("name", "John", Field.Store.NO, Field.Index.TOKENIZED);
Field f2 = new Field("name", "Doe", Field.Store.NO, Field.Index.TOKENIZED);
f1.setBoost(1.0f);
f2.setBoost(2.0f);
doc.add(f1);
doc.add(f2);
In the current version of Lucene, as far as I now, this does not work -
Allthough it would have been a very powerful feature.
The current solution is to make a firstname field and a lastname field, and
then make a complex query like this:
Input: Eric Doe
(firstname:Eric OR lastname:Eric^2) AND (firstname:Doe OR lastname:Doe^2)
The performance of such a query is quite slow, and it becomes even worse when
you have more than two fields and/or more words in the input string.
My questions:
1. Is there a better/faster solution to accomplish such a query?
2. Would it be possible to implement the described feature in a future version
of Lucene?
