RavenDb4 boost search bug

[Alexander Klaus]

Given two contact records with surnames "Elliot" and "Elliot-Murray", 

When run the following query 

from index 'Contacts/ForList' 

where Type = 'person'

and (boost(search(LastName, 'Elliot'), 1000) or boost(search(LastName, 'Elliot*'), 800))

Then results are received in a random order: "Elliot-Murray" may appear before "Elliot".

However, when the request above doesn't have additional filtering condition

from index 'Contacts/ForList' 

where boost(search(LastName, 'Elliot'), 1000) or boost(search(LastName, 'Elliot*'), 800)

Then results are received in the expected order: "Elliot" and then "Elliot-Murray".

Is it a bug?

P.S. If it makes any difference, the 'Analyzer' property on 'LastName' is set to 'WhitespaceAnalyzer'

Hi Alexander,

In order to get results ordered by specified boost factors you need to specify order by score() in the query.

 

By default Lucene returns the scores calculated according to specified boosting although we need to tell it to do the ordering.







[Arkadiusz Palinski]

We have modified the behavior of queries using boost() so they will return results ordered by score by default

Thank you! Will it be available in v4.0.6 or v4.1?
