problems retrieving term vectors using RealTimeGetHandler

[Scott C. Cote]

I’m working with term vectors via solr.  
Is there a way to configure the RealTimeGetHandler to return tv info?

Here is my environment info:

Scotts-MacBook-Air-2:solr_jetty scottccote$ java -version
java version "1.8.0_31"
Java(TM) SE Runtime Environment (build 1.8.0_31-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.31-b07, mixed mode)


Scotts-MacBook-Air-2:solr_jetty scottccote$ uname -a
Darwin Scotts-MacBook-Air-2.local 14.1.0 Darwin Kernel Version 14.1.0: Mon Dec 
22 23:10:38 PST 2014; root:xnu-2782.10.72~2/RELEASE_X86_64 x86_64


solr-4.10.3

Here is my attempted configuration

  
  

  true
  true
 

  tvComponent



Here is my request on the Solr Admin panel

qt is set to …  /get
Raw Query Parameters are set to … id=7&tv=true&tv.all=true

http://localhost:8983/solr/question/get?wt=json&indent=true&id=7&tv=true&tv.all=true
 


which generates the following response (with error)

more like this and term vectors

[Scott C. Cote]

Is there a way to configure the more like this query handler and also receive 
the corresponding term vectors? (tf-idf) ?

I tried by creating a “search component” for the term vectors and adding it to 
the mlt handler, but that did not work.

Here is what I tried:

 

  filteredText
  1
  1
  "list"
  true
 

  tvComponent

   

Now I realize that I could turn on the debug parameter but that does not 
contain the all of the tf/idf (at least not like the tv component provides)

Thanks,

SCott
