How do I implement the following query using Java ApI? Thanks!
curl -XGET http://localhost:9200/cs/csdl/_search?pretty=true -d '
{
"query":{
"function_score": {
"functions": [
{
"boost_factor": "-10",
"filter": {
"terms" : {"abbrev" : ["computer"] }
}
}
],
"query": {
"filtered": {
"query" : {
"multi_match" : {
"fields" : ["title"],
"query" : ["computer"]
}
},
"filter": {
"bool": {
"must": { "range": {
"pubdate": {
"gte": "1890-09" ,
"lte":"2014-08"
}
}
},
"must" : {
"terms" : {
"abbrev" : ["computer","annals","software"]
}
}
}
}
}
}
}
}
}'
