No highlighting of exact mach terms in analyzed field

Elastic Stack Elasticsearch
1

Hello All,

We perform exact match query on _all field and highlight an analyzed field
(text.), which contains the text:
{
"query" : {
"bool" : {
"must" : [ {
"bool" : {
"must" : [ {
"query_string" : {
"query" : ""published in 1937"",
"fields" : [ "_all" ],
"default_operator" : "and",
"boost" : 10.0
}
} ]
}
} ]
}
},
"filter" : {
"and" : {
"filters" : [ {
"and" : {
"filters" : [ {
"fquery" : {
"query" : {
"query_string" : {
"query" : ""58468762-fddc-44ea-af4a-270d00000080"",
"fields" : [ "_id" ]
}
},
"_cache" : true
}
} ]
}
} ]
}
},
"fields" : [ "_source", "_score" ],
"track_scores" : true,
"highlight" : {
"fields" : {
"text." : {
"fragment_size" : 50000,
"number_of_fragments" : 1000
}
}
}
}

We receive a document for result, but it has no highlighting. Sometimes
there is partial highlighting: for example if we search for "we live in NY"
the highlight is: live in NY</em and not the full match.

Can you please explain what do we do wrong?

Many Thanks.

Hi,

I'm not sure why you don't get highlights for this particular query, but
regarding the "we live in NY" example, I would guess that you are either
using the default analyzer or an analyzer that has stop words configured,
and this causes very common words such as "we" or "in" to be ignored when
highlighting. Here is an example that would highlight "we" and "in":
