我有一个名为 title 的字段，其中包含以下映射。
{
"title": {
"type": "string"
}
在为拼写检查执行术语建议时，它没有按预期给出结果。
对于查询lenovo a1000，它返回的结果如下。
[spell_suggestion] => Array
(
[0] => Array
(
[text] => lenovo
[offset] => 0
[length] => 6
[options] => Array
(
)
)
[1] => Array
(
[text] => a1000
[offset] => 7
[length] => 5
[options] => Array
(
[0] => Array
(
[text] => a1018
[score] => 0.6
[freq] => 1
)
[1] => Array
(
[text] => a102
[score] => 0.5
[freq] => 1
)
[2] => Array
(
[text] => a104
[score] => 0.5
[freq] => 1
)
[3] => Array
(
[text] => a108
[score] => 0.5
[freq] => 1
)
)
)
)
)
但索引的标题包含 lenovo a1000 。
我使用以下查询进行拼写检查。
{
"spell_suggestion": {
"text": "lenovo a1000",
"term": {
"field": "title",
"sort": "score",
"prefix_length": 3
}
}
}
为什么elasticsearch没有返回索引中已有的术语。 我做错了什么或丢失了吗？请建议。
答案 0 :(得分：0)
有一个选项suggest_mode，默认为：
missing: Only provide suggestions for suggest text terms that are not in the index. This is the default.
尝试将其更改为：
always: Suggest any matching suggestions based on terms in the suggest text.
