hi,

I'm now using ELS v.0.20.0. I have problem with highlighting.

My mapping:  
curl -XPUT "http://:9200$ip/business?pretty=1" -d '  
{  
"mappings": {  
"product": {  
"properties": {  
"productKey": {  
"type": "long"  
},  
"denotation": {  
"fields": {  
"denotation": {  
"type": "string",  
"analyzer": "full\_denotation"  
},  
"untouched" : {"type" : "string", "index" :  
"not\_analyzed"}  
},  
"type": "multi\_field"  
},  
"alias": {  
"properties" : {  
"value" : {  
"fields": {  
"value": {  
"type": "string",  
"analyzer": "full\_denotation"  
},  
"untouched" : {"type" : "string", "index" :  
"not\_analyzed"}  
},  
"type": "multi\_field"  
}  
},  
"type" : "nested"  
}  
}  
}  
},  
"settings": {  
"analysis": {  
"filter": {  
"denotation\_snow": {  
"type": "snowball",  
"language": "German2"  
}  
},  
"analyzer": {  
"full\_denotation": {  
"filter": [  
"standard",  
"lowercase",  
"icu\_folding",  
"denotation\_snow"  
],  
"type": "custom",  
"tokenizer": "standard"  
}  
}  
}  
}  
}'

* * *

My data:  
curl -XPUT 'http://$my\_ip:9200/business/product/1' -d '{  
"productKey":1,  
"denotation":"Schienenpersonenfernverkehr (SPFV)",  
"alias":[  
{"value":"Kombiverkehr, Strasse-Schiene"},  
{"value":"Kombiverkehr Strasse-Schiene, Containertransporte"},  
{"value":"Kombiverkehr Strasse-Schiene, Betontransporte"},  
{"value":"Kombiverkehr Strasse-Schiene,  
Festbrennstofftransporte"}]  
}'

* * *

## My query: { "query": { "bool": { "should": [{ "query\_string": { "query": "_strass_ _schien_", "fields": [ "denotation"], "use\_dis\_max": true, "default\_operator": "and", "allow\_leading\_wildcard": true } }, { "nested": { "query": { "query\_string": { "query": "_strass_ _schien_", "fields": ["alias.value"], "use\_dis\_max": true, "default\_operator": "and", "allow\_leading\_wildcard": true } }, "path": "alias" } } ], "minimum\_number\_should\_match": 1 } }, "highlight": { "require\_field\_match": true, "fields": { "denotation": {} } } }

Although all operators are AND, the highlight seems to be incorrect:  
Here is search result:  
{

```
took: 2
timed_out: false
_shards: {
    total: 5
    successful: 5
    failed: 0
}
hits: {
    total: 1
    max_score: 0.57735026
    hits: [
        {
            _index: business
            _type: product
            _id: 1
            _score: 0.57735026
            _source: {
                productKey: 1
                denotation: Schienenpersonenfernverkehr (SPFV)
                alias: [
                    {
                        value: Kombiverkehr, Strasse-Schiene
                    }
                    {
                        value: Kombiverkehr Strasse-Schiene,

```

Containertransporte  
}  
{  
value: Kombiverkehr Strasse-Schiene,  
Betontransporte  
}  
{  
value: Kombiverkehr Strasse-Schiene,  
Festbrennstofftransporte  
}  
]  
}  
highlight: {  
denotation: [  
_Schienenpersonenfernverkehr_ (SPFV)  
]  
}  
}  
]  
}  
}  
I wonder why the denotation ""Schienenpersonenfernverkehr" is  
highlighted when it just matched with 1 token (_schien_). If i  
separate my query into 2 queries, one for nested object only and one  
for query on denotation, both work fine.

The result I expected is:  
{  
took: 2  
timed\_out: false  
\_shards: {  
total: 5  
successful: 5  
failed: 0  
}  
hits: {  
total: 1  
max\_score: 0.57735026  
hits: [  
{  
\_index: business  
\_type: product  
\_id: 1  
\_score: 0.57735026  
\_source: {  
productKey: 1  
denotation: Schienenpersonenfernverkehr (SPFV)  
alias: [  
{  
value: Kombiverkehr, Strasse-Schiene  
}  
{  
value: Kombiverkehr Strasse-Schiene,  
Containertransporte  
}  
{  
value: Kombiverkehr Strasse-Schiene,  
Betontransporte  
}  
{  
value: Kombiverkehr Strasse-Schiene,  
Festbrennstofftransporte  
}  
]  
}  
}  
]  
}  
}

If anyone could help me on this, it's really appriciated, thanks so  
much.
