ElasticSearch wildcard highlighting with hyphen - elasticsearch

Question

I am having trouble with wildcard query. When i have some hyphen - it does not highlight anything after it. I played with highlight settings but did not found any solution yet. Is it normal behavior?
I am making some index:
PUT testhighlight
PUT testhighlight/_mapping/_doc
{
"properties": {
"title": {
"type": "text",
"term_vector": "with_positions_offsets"
},
"content": {
"type": "text",
"term_vector": "with_positions_offsets"
}
}
}
Then i create documents:
PUT testhighlight/_doc/1
{
"title": "1",
"content": "test-input"
}
PUT testhighlight/_doc/2
{
"title": "2",
"content": "test input"
}
PUT testhighlight/_doc/3
{
"title": "3",
"content": "testinput"
}
Then i execute this search request:
GET testhighlight/_search
{
"query": {
"bool": {
"must": [
{
"query_string": {
"fields": [
"title",
"content"
],
"query": "test*"
}
}
]
}
},
"highlight": {
"fields": {
"content": {
"boundary_max_scan": 10,
"fragment_offset": 5,
"fragment_size": 250,
"type": "fvh",
"number_of_fragments": 5,
"order": "score",
"boundary_scanner": "word",
"post_tags": [
"</span>"
],
"pre_tags": [
"""<span class="highlight-search">"""
]
}
}
}
}
It returns these hits:
"hits": [
{
"_index": "testhighlight",
"_type": "_doc",
"_id": "2",
"_score": 1.0,
"_source": {
"title": "2",
"content": "test input"
},
"highlight": {
"content": [
"""<span class="highlight-search">test</span> input"""
]
}
},
{
"_index": "testhighlight",
"_type": "_doc",
"_id": "1",
"_score": 1.0,
"_source": {
"title": "1",
"content": "test-input"
},
"highlight": {
"content": [
"""<span class="highlight-search">test</span>-input"""
]
}
},
{
"_index": "testhighlight",
"_type": "_doc",
"_id": "3",
"_score": 1.0,
"_source": {
"title": "3",
"content": "testinput"
},
"highlight": {
"content": [
"""<span class="highlight-search">testinput</span>"""
]
}
}
]
It looks alright, but didn't highlighted the whole "test-input" in document with ID 1. Is there any way to do so?
