Hadrien HUGOT updated LUCENENET-513:
------------------------------------
Description:
Regression between Lucene 2.9.4g and Lucene 3.0.3 in the method GetFieldQuery
of MultiFieldQueryParser with the boosts factor.
{noformat}
public class MultiFieldQueryParser : QueryParser {
protected internal override Query GetFieldQuery(string field, string
queryText, int slop)
{
...
//If the user passes a map of boosts
if (boosts != null)
{
//Get the boost from the map and apply them
Single boost = boosts[fields[i]];
q.Boost = boost;
}
...
{noformat}
If all fields don't have a boost factor an exception is throw by "Single boost
= boosts[fields[i]];"
In version 2.9.4g, a check was performed, and no boost were apply if the field
is not boosted.
I added a patch with the following modification:
{noformat}
//Get the boost and apply them if exists
float boost;
if (boosts.TryGetValue(fields[i], out boost))
q.Boost = boost;
{noformat}
was:
