Nested documents search

Elastic Stack Elasticsearch
1

All,

I have nested documents with the following structure

rtext :
{
id : integer,
value : string
}

rdata
{
id : integer.
value : float
}

I'm trying to search all the documents with id = 1 and value = xxx

{
"filter": {
"nested": {
"path": "rtext",
"query": {
"bool": {
"must": [
{
"term": {
"rtext.textmapid": "1"
}
},
{
"term": {
"rtext.textvalue": "xxx"
}
}
]
}
}
}
}
}

The query returns 0 results. But If the ran the same rdata which has value
type as float it comes back with results. Am I missing anything ?

Thanks,
Abhishek

Hey,

can you maybe provide a full minimal example including mapping, indexing
data and full queries. This would allow other people to reproduce your
issue easily and see what is wrong. Also including the case where
everything works, would be useful.

Thanks!

Alex,

Thanks for the reply.

My Mappings
{
"response": {
"properties": {
"rtext": {
"type": "nested",
"properties": {
"textmapid": {
"type": "integer"
},
"textvalue": {
"type": "string"
}
}
}
}
}
}

Sample data

{
"rtext" : [
{
"textmapid" : 1,
"textvalue" : "Jennifer"
},
{
"textmapid" : 2,
"textvalue" : "Adam"
}
]
}

My query

Term filter does not work.

{
"filter": {
"nested": {
"path": "rtext",
"query": {
"bool": {
"must": [
{
"term": {
"rtext.textvalue": "Jennifer"
}
},
{
"term": {
"rtext.textmapid": 1
}
}
]
}
}
}
}
}

Match filter works
{
"filter": {
"nested": {
"path": "rtext",
"query": {
"bool": {
"must": [
{
"match": {
"rtext.textvalue": "Jennifer"
}
},
{
"term": {
"rtext.textmapid": 1
}
}
]
}
}
}
}
}

Prefix filter doesn't work but match_phrase_prefix works.

1)Term filter doesn't work but match filter works why ?
2) Prefix filter doesn't work but match_phrase_prefix works. What the
difference between match and match_phrase ?
3) How do I write a begins with and ends with filter ? I tried regex filter
with "Jen." and \bJen(.)\b for begins with it didnot work ?
4) How do I write a exists and missing filter they dont work either.

{
"filter": {
"nested": {
"path": "rtext",
"query": {
"bool": {
"must": [
{
"exists": {
"field": "rtext.textvalue"
}
},
{
"term": {
"rtext.textmapid": 1
}
}
]
}
}
}
}
}

Thanks,
Abhishek

1)Term filter doesn't work but match filter works why ?

Because term filter doesn't analyze the search string and match filter
does. There is not token "Jennifer" in your index, only "jennifer".

  1. Prefix filter doesn't work but match_phrase_prefix works. What the
    difference between match and match_phrase ?

See 1)

  1. How do I write a begins with and ends with filter ? I tried regex filter
    with "Jen." and \bJen(.)\b for begins with it didnot work ?

You might be better using EdgeNGrams here, but at least lowercase your term.

  1. How do I write a exists and missing filter they dont work either.

exists is a filter (not query) so it should be:

{
"filter": {
"nested": {
"path": "rtext",

  •  "filter": {*
  "bool": {
    "must": [
      {
        "exists": {
          "field": "rtext.textvalue"
        }
      },
      {
        "term": {
          "rtext.textmapid": 1
        }
      }
    ]
  }
}
    }
    }
    }
