boost last modified documents doesn't work

[Fabian Smagghe <f....@uliege.be>]

Dear  all,
In solr, I want to show the last modified documents first. I use 
exemples in Solr guide 
(https://solr.apache.org/guide/8_1/the-dismax-query-parser.html#bf-boost-functions-parameter) 
and in the result I don't have the last modified documents first...
what is the problem? can you help me?

Thanks!

*Query**:*

/select?q=*:*&rows=50&bf=recip(rord(lastModified),1,1000,1000)
.. or ...
/select?q=*:*&rows=50&bq={!func}recip(rord(lastModified),1,1000,1000)


*SOLR managed-schema:*

|<field name="lastModified" type="pdate" indexed="true" stored="true" 
default="NOW" multiValued="false"/> ||<fieldType name="pdate" class="solr.DatePointField" docValues="true"/>|

you can look at the detailed score calculation to see the ranking of results using debug.explain.structured=true in query
