Joshua Pantony updated SOLR-8542:
---------------------------------
Description:
This is a ticket to integrate learning to rank machine learning models into
Solr. Solr Learning to Rank (LTR) provides a way for you to extract features
directly inside Solr for use in training a machine learned model. You can then
deploy that model to Solr and use it to rerank your top X search results. This
concept was previously presented by the authors at Lucene/Solr Revolution 2015
(
http://www.slideshare.net/lucidworks/learning-to-rank-in-solr-presented-by-michael-nilsson-diego-ceccarelli-bloomberg-lp
).
The attached code was jointly worked on by Joshua Pantony, Michael Nilsson,
David Grohmann and Diego Ceccarelli.
[Read through the
README|https://github.com/bloomberg/lucene-solr/tree/master-ltr-plugin-release/solr/contrib/ltr]
for a tutorial on using the plugin, in addition to how to train your own
external model.

Any chance this could make it into a 5x release? We've also attached
documentation as a github MD file, but are happy to convert to a desired format.
h3. Test the plugin with solr/example/techproducts in 6 steps
Solr provides some simple example of indices. In order to test the plugin with
the techproducts example please follow these steps
h4. 1. compile solr and the examples
cd solr
ant dist
ant example
h4. 2. run the example
./bin/solr -e techproducts
h4. 3. stop it and install the plugin:
./bin/solr stop
mkdir example/techproducts/solr/techproducts/lib
cp build/contrib/ltr/lucene-ltr-6.0.0-SNAPSHOT.jar
example/techproducts/solr/techproducts/lib/
cp contrib/ltr/example/solrconfig.xml
example/techproducts/solr/techproducts/conf/
h4. 4. run the example again
./bin/solr -e techproducts
h4. 5. index some features and a model
curl -XPUT 'http://localhost:8983/solr/techproducts/schema/fstore'
--data-binary "@./contrib/ltr/example/techproducts-features.json" -H
'Content-type:application/json'
curl -XPUT 'http://localhost:8983/solr/techproducts/schema/mstore'
--data-binary "@./contrib/ltr/example/techproducts-model.json" -H
'Content-type:application/json'
h4. 6. have fun !
*access to the default feature store*
http://localhost:8983/solr/techproducts/schema/fstore/_DEFAULT_
*access to the model store*
http://localhost:8983/solr/techproducts/schema/mstore
*perform a query using the model, and retrieve the features*
http://localhost:8983/solr/techproducts/query?indent=on&q=test&wt=json&rq={!ltr%20model=svm%20reRankDocs=25%20efi.query=%27test%27}&fl=*,[features],price,score,name&fv=true
