I have the parameter name
as a text:
{
"mappings": {
"_doc": {
"properties": {
"name": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
}
}
}
}
Because of the nature of text
type in ElasticSearch, matchs every word on the phrase. That's why in some cases I get the next results:
POST /example-tags/_search
{
"query": {
"match": {
"name": "Jordan Rudess was born in 1956"
}
}
}
// Results
{
"took" : 28,
"timed_out" : false,
"_shards" : {
"total" : 2,
"successful" : 2,
"skipped" : 0,
"failed" : 0
},
"hits" : {
"total" : {
"value" : 1,
"relation" : "eq"
},
"max_score" : 2.1596613,
"hits" : [
{
"_index" : "example-tags",
"_type" : "_doc",
"_id" : "6101e538bc8ec610aff699e4",
"_score" : 4.1596613,
"_source" : {
"name" : "Jordan Rudess"
}
},
{
"_index" : "example-tags",
"_type" : "_doc",
"_id" : "610123538bc8ec61034ff699e4",
"_score" : 4.1796613,
"_source" : {
"name" : "Alice in Chains"
}
},
]
}
}
As you can see, in the text Jordan Rudess was born in 1956
I get the result Alice in Chains
just for the word in
. I want to avoid this behaviour.
If I try:
POST /example-tags/_search
{
"query": {
"match_phrase": {
"name": "Dream Theater keyboardist's Jordan Rudess was born in 1956"
}
}
}
// Results
{
"took" : 2,
"timed_out" : false,
"_shards" : {
"total" : 1,
"successful" : 1,
"skipped" : 0,
"failed" : 0
},
"hits" : {
"total" : {
"value" : 0,
"relation" : "eq"
},
"max_score" : null,
"hits" : [ ]
}
}
So, in the past example I was expecting to get the Jordan Rudess
tag name but I get empty results.
I need to get the maximum ocurrences in tag.name
of consecutive words in a phrase. How can I achieve that?
