How to make exact values and match queries on same field in elasticsearch?

You can analyze the same field processNumber in different ways using the fields property in the mapping:

For example if you want the analyzed and unanalyzed version of ProcessNumber the mapping would be :

 {   "type_name": {      "properties": {         "processNumber": {            "type": "string",            "index": "not_analyzed",            "fields": {               "analyzed": {                  "type": "string",                  "index": "analyzed"               }            }         }      }   }}

Where the not-analyzed field is referred in query as processNumber .

To refer to the analyzed view of the field use processNumber.analyzed

The queries for terms 11/201, 11 etc would be :

Example Filter:

 { "query" : { "filtered" : { "filter" : { "term" : { "processNumber" : "11/2014" } } } } }

Term filter it does not analyze the search string so an input would be matched as it is with the fields inverted index in this case : 11/2014 against the field.

Example Match_Phrase_prefix:

{ "query": { "match_phrase_prefix": { "processNumber": "11/201" } } }

match_phrase_prefix tries to check if the last term in the phrase is a prefix of terms in index . It analyzes the search string if an analyzer is specified. This is the reason you need to use the unanalyzed version of the field here . If we use processNumber.analyzed search queries such as 11-201 , 11|201 would also match

example match :

  { "query": { "match": { "processNumber.analyzed": "11" } } }

This is straight forward match since default analyzer (usually standard analyzer) will tokenize 11/2014 to terms 11, 2014 .

You can use the analyze api to see how a particular text gets analyzed by default analyzer.

curl -XPOST "http://<machine>/_analyze?text=11/2014"
