Query string with wild card not returning the expected results , all the times

I am using ES 6.4 .
When I tried
GET /_search?size=10&from=0
{
"_source":["name"],
"query":{
"query_string" : {
"query" : "(some1.some.string.test.query.1234.test) AND (status:active) AND NOT (xyz OR abc)",
"fields" : ["name"]
}
}
}

It is returning expected results.

But when I tried ,
GET /_search?size=10&from=0
{
"_source":["name"],
"query":{
"query_string" : {
"query" : "(some1.some.string.test.query.1234.) AND (status:active) AND NOT (xyz OR abc)",
"fields" : ["name"]
}
}
}

It is returning null, even though matches are there.
{
"took": 38,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"skipped": 0,
"failed": 0
},
"hits": {
"total": 0,
"max_score": null,
"hits":
}
}

Can any of you give me more idea on what happens in this case, when wild card is used along with longer strings?
Thanks in advance.

Hi @sngs1

I think you need to escape the "*" character as follows:

some1.some.string.test.query.1234.\*

I had to do this too with ELK version 6.6.1. Since version 7.x (I dont remember exactly which one) it is no longer necessary to escape.

Hope this helps.

Thanks for the reply. I have already tried using backslash.
But single backslash is not supported

\*some1.some.string.test.query.1234.\*
"type": "json_parse_exception",
"reason": "Unrecognized character escape '*' (code 42)\n at [Source: org.elasticsearch.transport.netty4.ByteBufStreamInput@55a18add; line: 5, column: 21]"

So I tried
\\*some1.some.string.test.query.1234.\\* with double backslash, and that gave me the expected results.

But the same on a small string (sub string of the same) didn't returned any results.
\\*some1.\\*
{
"took": 1,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"skipped": 0,
"failed": 0
},
"hits": {
"total": 0,
"max_score": null,
"hits":
}
}

Hi @sngs1

Have you tried using the same string in the Kibana search mask?

No, I will try.
It is also not returning the expected results if we search for some string like
"@xyz.com"
