Skywalking version 6.6 with Elasticsearch 6.8 for storage.
Firstly, on the "trace" page of skywaking UI，try to search a endpoint name
like "/xnv/abc_def/QW030384" , and the results are not expected, something like:
```
/xnv/abc_def/QW051234
/xnv/abc_def/QW051235
...
```
Secondly, try to analyzer the above endpoint name with the default
oap_analyzer using kibana devtool:
```bash
GET sw_segment-20200610/_analyze
{
"text": "/xnv/abc_def/QW030384",
"analyzer" : "oap_analyzer"
}
```
the results are:
```
{
"tokens" : [
{
"token" : "xnv",
"start_offset" : 1,
"end_offset" : 4,
"type" : "word",
"position" : 0
},
{
"token" : "abc",
"start_offset" : 5,
"end_offset" : 8,
"type" : "word",
"position" : 1
},
{
"token" : "def",
"start_offset" : 9,
"end_offset" : 12,
"type" : "word",
"position" : 2
},
{
"token" : "qw",
"start_offset" : 13,
"end_offset" : 15,
"type" : "word",
"position" : 3
}
]
}
```
The above results say that, with the oap_analyzer, the endpoint name
"/xnv/abc_def/QW030384" is analyzed to some tokens: "xnv" "abc" "def" "qw",
**the numbers in the endpoint name are ignored.**
