External file field in Apache Solr

I am trying to use ExternalFileField in ApacheSolr for external scoring.

I am using the config example. Basically, I want to set ratings for elements using their identifiers.

I set the fieldType idRankFile and the idRank field in schema.xml:

<fieldType name="idRankFile" keyField="id" defVal="0" stored="true" indexed="true" class="solr.ExternalFileField" valType="pfloat" />
<field name="idRank" type="idRankFile" indexed="true" stored="true" />

And he made a file called external_idRank in / solr / example / solr / data with the following contents:

F8V7067-APL-KIT = 1.0
IW-02 = 10.0
9885A004 = 100.0
SOLR1000 = 1000.0

(This assigns idRank values ​​for various identifiers)

Now I run the following query:

http: // localhost: 8983 / solr / select /? indent = on & q = car% 20power% 20adapter% 20_val_:% 22product (idRank, 1)% 22 & fl = name, id

This should basically return the results in the order of their idRanks. However, it is not.

Any ideas?
