Sto cercando di creare una query nella ricerca elastica per cercare all'interno del testo di più campi, ad esempio: Titolo e descrizione sono i campi e voglio cercare "obama", " mondo "," notizie "all'interno di questi 3 campi. Ho provato a cercare e ho trovato le informazioni nel sito web Elastico qui:
http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/query-dsl-multi-match-query.html#_literal_fields_literal_and_per_field_boosting ma il problema è quando ho provato queste strutture si producono errori:
Prime:Ricerca elastica più parole chiave in più campi
{
"multi_match" : {
"query": "obama world news",
"type": "cross_fields",
"fields": [ "Title", "Description" ],
"operator": "and"
}
}
produce errore come questo:
{
"error": "SearchPhaseExecutionException[Failed to execute phase [query], all shards failed; shardFailures {[0CTkBM0pQGK1MzYEDlrpcQ][republishan2][0]: SearchParseException[[republishan2][0]: from[-1],size[-1]: Parse Failure [Failed to parse source [ {\n \"multi_match\" : {\n \"query\": \"obama world news\",\n \"type\": \"cross_fields\",\n \"fields\": [ \"Title\", \"Description\" ],\n \"operator\": \"and\"\n }\n }]]]; nested: SearchParseException[[republishan2][0]: from[-1],size[-1]: Parse Failure [No parser for element [multi_match]]]; }{[0CTkBM0pQGK1MzYEDlrpcQ][republishan2][3]: SearchParseException[[republishan2][3]: from[-1],size[-1]: Parse Failure [Failed to parse source [ {\n \"multi_match\" : {\n \"query\": \"obama world news\",\n \"type\": \"cross_fields\",\n \"fields\": [ \"Title\", \"Description\" ],\n \"operator\": \"and\"\n }\n }]]]; nested: SearchParseException[[republishan2][3]: from[-1],size[-1]: Parse Failure [No parser for element [multi_match]]]; }{[0CTkBM0pQGK1MzYEDlrpcQ][republishan2][4]: SearchParseException[[republishan2][4]: from[-1],size[-1]: Parse Failure [Failed to parse source [ {\n \"multi_match\" : {\n \"query\": \"obama world news\",\n \"type\": \"cross_fields\",\n \"fields\": [ \"Title\", \"Description\" ],\n \"operator\": \"and\"\n }\n }]]]; nested: SearchParseException[[republishan2][4]: from[-1],size[-1]: Parse Failure [No parser for element [multi_match]]]; }{[0CTkBM0pQGK1MzYEDlrpcQ][republishan2][1]: SearchParseException[[republishan2][1]: from[-1],size[-1]: Parse Failure [Failed to parse source [ {\n \"multi_match\" : {\n \"query\": \"obama world news\",\n \"type\": \"cross_fields\",\n \"fields\": [ \"Title\", \"Description\" ],\n \"operator\": \"and\"\n }\n }]]]; nested: SearchParseException[[republishan2][1]: from[-1],size[-1]: Parse Failure [No parser for element [multi_match]]]; }{[0CTkBM0pQGK1MzYEDlrpcQ][republishan2][2]: SearchParseException[[republishan2][2]: from[-1],size[-1]: Parse Failure [Failed to parse source [ {\n \"multi_match\" : {\n \"query\": \"obama world news\",\n \"type\": \"cross_fields\",\n \"fields\": [ \"Title\", \"Description\" ],\n \"operator\": \"and\"\n }\n }]]]; nested: SearchParseException[[republishan2][2]: from[-1],size[-1]: Parse Failure [No parser for element [multi_match]]]; }]",
"status": 400
}
anche io ho provato questa query:
{
"sort": {
"re_max": {
"order": "desc"
}
},
"query": {
"multi_match" : {
"query": "obama world news",
"type": "cross_fields",
"fields": [ "Title", "Description" ],
"operator": "and"
}
},
"from": 0,
"size": 30}
}
E questo è il risultato:

sto usando cliente Postman Riposo per eseguire la query. Qual è il problema con il mio codice?
