创建 mapping
curl -XPOST http://localhost:9200/news/fulltext/_mapping -H 'Content-Type:application/json' -d '
{
"properties": {
"title": {
"type": "text",
"analyzer": "ik_max_word",
"search_analyzer": "ik_max_word"
}
"content": {
"type": "text",
"analyzer": "ik_max_word",
"search_analyzer": "ik_max_word"
}
}
}'
全文分词检索高亮使用
curl -XPOST http://localhost:9200/news/fulltext/_search?pretty -H 'Content-Type:application/json' -d'
{
"query" : { "match" : { "content" : "渔船每天行驶多远" }},
"highlight" : {
"pre_tags" : ["<em1>", "<em2>"],
"post_tags" : ["</em1>", "</em2>"],
"fields" : {
"content" : {}
}
}
}'
sort
stored_fields：
curl -X GET "localhost:9200/_search" -H 'Content-Type: application/json' -d'
