Hi Krishan,
What if you remove the query() wrapping?
{
"name": "phraseMatch",
"class": "org.apache.solr.ltr.feature.SolrFeature",
"params": {
"q": "{!complexphrase inOrder=true}fieldName:${input}"
},
"store": "_DEFAULT_"
}
or even:
{
"name": "phraseMatch",
"class": "org.apache.solr.ltr.feature.SolrFeature",
"params": {
"q": "{!complexphrase inOrder=true df=fieldName}${input}"
},
"store": "_DEFAULT_"
}
