Hi I have read the concept of "Learning To Rank". I see the Example: /path/myFeatures.json
{ "name" : "documentRecency", "class" : "org.apache.solr.ltr.feature.SolrFeature", "params" : { "q" : "{!func}recip( ms(NOW,last_modified), 3.16e-11, 1, 1)" } }, { "name" : "isBook", "class" : "org.apache.solr.ltr.feature.SolrFeature", "params" : { "fq": ["{!terms f=cat}book"] } } I want to make feature like q=title:"Test with some GB18030 encoded characters". Can I make? Can I search sentence "test book" in terms like "fq": ["{!terms f=cat}test book"]? I want to use q and fq same like normal in feature.
