Help with Query String Query

Elastic Stack Elasticsearch
4

Hello,

From what I understand by reading these two:
http://www.mail-archive.com/java-user@lucene.apache.org/msg00008.html
https://issues.apache.org/jira/browse/LUCENE-1823

This seems to be an issue with the way Lucene parses queries, which is
not resolved yet. So I think the best approach here is to use explicit
grouping through those parenthesis.

Best regards,
Radu

Thanks Raffaele, grouping works. I agree with you, from what I've learn, AND
has higher precedence, so that means the query should also work without
grouping right? Unless i'm missing something fundamental?

I am not sure AND has a higher priority than OR in Lucene. I would try
"grouping":

"some AND (random OR other)"

Hi,

I'm trying to do text search with boolean using QueryString query but
it's not hehaving as expected.

Let's say i have a field call headline in my database and i have the
following two headlines...

headline 1: "some random headline"
headline 2: "some other headline"

{"query_string":{
"default_field":"headline",
"query":"some AND random OR other"}
}

The above query should return both docs right? If not, what is wrong
with my query?

If i can change the query to "some OR random OR other", then it does
return both docs, but why didn't the AND work?

Thanks in advance for the help.
