Simple query text field with spaces and * issues after upgrade #31150
Description
Elasticsearch version (bin/elasticsearch --version): 6.2.4
Plugins installed: []
JVM version (java -version): 1.8.0_171
OS version (uname -a if on a Unix-like system): Windows sever 2012 R2
Description of the problem including expected versus actual behavior:
The simple query string command does not return expected results when the query contains a space and a wildcard e.g ( "Test *"). The same query format works in version 5.6.8 and was noticed after an upgrade.
Steps to reproduce:
Here are the steps (using Kibana) to set up an index to reproduce the issue
PUT test_query
{
"mappings": {
"test_type": {
"_source": {
"enabled": true
},
"properties": {
"my_field": {
"type": "text",
"analyzer": "standard"
}
}
}
}
}
POST /test_query/test_type
{
"my_field": "Test Value Here"
}
POST /test_query/test_type
{
"my_field": "Testing different"
}
POST test_query/_refresh
GET test_query/_search
{
"query": {
"simple_query_string": {
"fields": [
"my_field"
],
"query": "Test*",
"default_operator": "and"
}
}
}
GET test_query/_search
{
"query": {
"simple_query_string": {
"fields": [
"my_field"
],
"query": "Test *",
"default_operator": "and"
}
}
}
The query "Test*" returns the document as expected. However "Test *" does not work in version 6.2.4. In version 5.6.8, both queries return results as expected using the same standard analyzer for the field.
Expected 1 hit, actually received 0 hits.
Was there an intentional change made that would impact this query in version 6.X?
