When I query my data for _all fields, Elasticsearch returns two documents (both with only one field in the document). But when I do the same query except I change the field being queried from _all to the name of one of the fields in the returned documents, Elasticsearch returns nothing. This seems to occur with a query_string query as well as the match query shown here. Any ideas what this is occurring and how to fix it?
This is the mapping
analyzertestpatternsemi: {
mappings: {
content: {
properties: {
field: {
type: string
store: true
term_vector: with_positions_offsets
index_analyzer: analyzer_name
}
field2: {
type: string
store: true
index_analyzer: analyzer_name
}
}
}
}
}
This is the settings
{
analyzertestpatternsemi: {
settings: {
index: {
uuid: _W55phRKQ1GylWU5JleArg
analysis: {
analyzer: {
whitespace: {
type: custom
fields: [
lowercase
]
tokenizer: whitespace
}
analyzer_name: {
preserve_original: true
type: pattern
pattern: ;
}
}
}
number_of_replicas: 1
number_of_shards: 5

}
}
}
}
The Docs
{
_index: analyzertestpatternsemi
_type: content
_id: 3
_version: 1
found: true
_source: {
field2: Hello, I am Paul; George
}
}
and
{
_index: analyzertestpatternsemi
_type: content
_id: 2
_version: 1
found: true
_source: {
field: Hello, I am Paul; George
}
}
Getting the term vectors for _id gives
george and hello, i am paul
