Uwe Schindler updated LUCENE-3347:
----------------------------------
Description:
The lucene XML parser seems to convert user defined boosting back to default
1.0 and thus boosting value is dropped from the query...
e.g.
{code:xml}
<BooleanQuery>
<Clause occurs="must">
<BooleanQuery>
<Clause occurs="should">
<UserQuery fieldName="Vehicle.Colour">red^66
blue~^8</UserQuery>
</Clause>
</BooleanQuery>
</Clause>
<Clause occurs="should">
<BooleanQuery>
<Clause occurs="should">
<UserQuery
fieldName="Vehicle.Colour">black^0.01</UserQuery>
</Clause>
</BooleanQuery>
</Clause>
</BooleanQuery>
{code}
produces a lucene query: +( ( Vehicle.Colour:red^66 Vehicle.Colour:blue~0.5^8 )
) ( Vehicle.Colour:black )
The expected query : +( ( Vehicle.Colour:red^66 Vehicle.Colour:blue~0.5^8 ) ) (
Vehicle.Colour:black^0.01 )
I have developed a work around by modifying line 77 of
UserInputQueryBuilder.java
from:
{code:java}
q.setBoost(DOMUtils.getAttribute(e,"boost",1.0f));
{code}
to:
{code:java}
q.setBoost( DOMUtils.getAttribute( e, "boost", q.getBoost() ) );
{code}
was:
