Subject Very slow query when boosting involve with EnternalFileField
Date Wed, 20 Mar 2013 06:58:08 GMT
Hi everyone,

I have a problem and have no luck to figure out.

When I issue a query to
Query 1

Query 2

The difference between two query is "boost".
The boost function of Query 2 using a field named ranking and this field is
External file is key=value pair about 10000 lines.

Execution time
Query 1-->100ms
Query 2-->2300ms

I tried to issue Query 3 and change ranking to a constant "1"

Execution time
Query 3-->110ms

one thing I can sure that involved with externalFileField will slow down
query execution time significantly. But I have no idea how to solve this
problem as my boost function must calculate value of ranking field.

Please help on this.

PS: I'm using SOLR-4.1
