Subject [jira] [Commented] (SOLR-3963) SOLR: map() does not allow passing recip() sub-functions
Date Thu, 18 Oct 2012 23:04:03 GMT

    [ https://issues.apache.org/jira/browse/SOLR-3963?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13479456#comment-13479456
] 

Hoss Man commented on SOLR-3963:
--------------------------------

Bill: i'm not understanding the error message you've pposted at all -- it seems to be from
some C# client code used to talk to solr?

can you post the actual error message logged by solr? preferably with the (java) stack trace?

FWIW: https://wiki.apache.org/solr/FunctionQuery#map

bq. map(x,min,max,target) maps any values of the function x that fall within min and max inclusive
to target. *min,max,target are constants.* It outputs the field's value if it does not fall
between min and max. 

...it may be possible to modify the function so min/max/target could be functions, but as
designed it does not and you _should_ get a clear error message about that.

> I want to do:
> boost=map(achievement_count,1,1000,recip(achievement_count,-.5,10,25),1)
> I want to return recip(achievement_count,-.5,10,25) if achievement_count is between 1
and 1,000. FOr any other values I want to return 1.
> I cannot get it to work. I get the error below. Interesting this does work:
> boost=recip(map(achievement_count,0,0,-200),-.5,10,25)
> It almost appears that map() cannot take a function.
