How to obtain the Explained output programmatically ?

Hi,

I need to use some detailed information of the explained result in Solr
search.

Here is one example:

*
http://localhost:8983/solr/select/?q=GB&version=2.2&start=0&rows=10&indent=on&debugQuery=true&fl=id,score
*

    <str name="6H500F0">
0.18314168 = (MATCH) sum of:
  0.18314168 = (MATCH) weight(text:gb in 1), product of:
    0.35845062 = queryWeight(text:gb), product of:
      2.3121865 = idf(docFreq=6, numDocs=26)
      0.15502669 = queryNorm
    0.5109258 = (MATCH) fieldWeight(text:gb in 1), product of:
      1.4142135 = tf(termFreq(text:gb)=2)
      2.3121865 = idf(docFreq=6, numDocs=26)
      0.15625 = fieldNorm(field=text, doc=1)
</str>

I could see the explained result by clicking the "toggle explain" button in
the web browser.   Is there a way to access the explained output
programmatically?


Regards,
David

If we're talking SolrJ here, I *think* you can
get it from the NamedList<Object> returned
from SolrResponse.getResponse, but I confess
I haven't tried it.

If not SolrJ, what is your plugin doing? And
where to you expect your plugin to be in
the query process?

Best
Erick

Thanks Hoss!

debug.explain.structured<https://wiki.apache.org/solr/CommonQueryParameters#debug.explain.structured>
is
definitely helpful.  It adds some structure to the plain explained output.
Is there a way to access these structured outputs in Java code (e.g., via
Solr plugin class)?
We could write a HTML parse to examine the output in the browser, but it's
probably no the best way to do that.
