弹性/亮点 [英] elasticsearch / lucene highlight
问题描述
我的映射是:
code>mongodocid:{
boost:1.0,
store:yes,
type:string
},
fulltext:{
boost:1.0,
index:analyze,
store:yes,
type string,
term_vector:with_positions_offsets
}
突出显示完整的全文我将 number_of_framgments
设置为0
如果我执行以下类似Lucene的字符串查询:
{
highlight:{
pre_tags:< b>,
fields:{
fulltext:{
number_of_fragments:0
}
},
post_tags:< / b> ;
},
query:{
query_string:{
query:fulltext:test
}
},
size:100
}
对于结果集中的一些文档,突出显示的全文小于全文本身。
由于我将 number_of_fragments
设置为0和 pre_tags
/ post_tags
被添加,这不应该发生。
现在出现了奇怪的行为:如果我只是通过这样做搜索一个失败的元素:
{
highlight:{
pre_tags:< b>,
字段:{
fulltext:{
number_of_fragments:0
}
},
post_tags:< / b>
},
query:{
query_string:{
query:fulltext:test AND mongodocid:4d0a861c2ebef6032c00b1ec
}
},
size:100
}
然后一切正常。
任何想法?
在0.14.0(参见#479 )。截至撰写0.14.0尚未发布,您可以尝试高手吗?
I'm using ElasticSearch to index documents.
My mapping is:
"mongodocid": {
"boost": 1.0,
"store": "yes",
"type": "string"
},
"fulltext": {
"boost": 1.0,
"index": "analyzed",
"store": "yes",
"type": "string",
"term_vector": "with_positions_offsets"
}
To highlight the complete fulltext I am setting number_of_framgments
to 0.
If I do the following Lucene-like string query:
{
"highlight": {
"pre_tags": "<b>",
"fields": {
"fulltext": {
"number_of_fragments": 0
}
},
"post_tags": "</b>"
},
"query": {
"query_string": {
"query": "fulltext:test"
}
},
"size": 100
}
For some documents in the result set the length of the highlighted fulltext is smaller than the fulltext itself.
Since I am setting number_of_fragments
to 0 and pre_tags
/post_tags
are added this should not happen.
Now comes the strange behaviour: If I only search for one of the failing elements by doing this:
{
"highlight": {
"pre_tags": "<b>",
"fields": {
"fulltext": {
"number_of_fragments": 0
}
},
"post_tags": "</b>"
},
"query": {
"query_string": {
"query": "fulltext:test AND mongodocid:4d0a861c2ebef6032c00b1ec"
}
},
"size": 100
}
then all works fine.
Any ideas?
Sounds like issue which has been fixed in 0.14.0 (see #479). As of writing the 0.14.0 hasn't been released yet, can you try master?
