Meaning dot/ dash at elasticsearch

[Sharon_wsf (雪中的凤凰)]

Hi Team,

POST news/bursa/_search{ "query": { "bool": { "must": [ { "multi_match": { "query": "0108.KL" , "fields": [  "stkno", "tag"  ,"content"  ,"htext"  ] , "operator": "or"  } } , { "range": { "CDate": {  "gt": "2014-04-01" ,  "lte": "2017-04-26T23:59:59"  } } }  ] } },  "from": 0, "size": 1000, "sort": [ { "CDate": { "order": "desc" } } ] }

My comment as above, when i search "0108.KL", the result not expected, it will find all result i don't want. If my query change to "0108" it can find the data i need.
Same also dash(-).

What the meaning of dot (.) and dash(-) at elasticsearch?

That would be because of analysis. What sort of field did you map it as?

Please don't post pictures of text, they are difficult to read and some people may not be even able to see them.
