Why "generate.min.score" does not work?

[Yongyao Jiang]

Hi,

I am using scoring-similarity plugin. After setting the generate.min.score
to 0.05, and indexing all the pages (with its score) into Elastic, I can
still observe many web pages whose scores are below 0.05.

<property>
  <name>generate.min.score</name>
  <value>0.05</value>
  <description>Select only entries with a score larger than
  generate.min.score.</description>
</property>

Below is the result of a simple aggregation of "score" in ES,
        {
               "key": "20170417215917",
               "doc_count": 200,
               "Stats": {
                  "count": 200,
                  "min": 0,
                  "max": 0.019184709,
                  "avg": 0.0012828724450000002,
                  "sum": 0.256574489
               }
            }

Thanks,
