lucene - Search for a numeric range inside string in elastic search -


i wanted search numeric expression in elastic search.

example

indent code 4.8663 spaces indent code 121.232 spaces indent code 12.3232 spaces

example query

get string "indent code between 1 , 100"

it should 1st , 3rd not 2nd.

                    {                         "span_near": {                             "in_order": 1,                             "clauses": [                                 {                                     "span_term": {                                         "request": "indent"                                     }                                 },                                 {                                     "span_term": {                                         "request": "code"                                     }                                 }                                 ,                                 {                                     "span_multi": {                                             "match":{                                                 "range": {                                                     "request": {                                                         "to": 100,                                                         "from": 1                                                     }                                                 }                                         }                                     }                                 }                             ],                             "slop": 0,                             "collect_payloads": 0                         }                     }

giving wrong result. comparing using termrangequery rather numericrangequery.

if can either replace float numbers integer numbers (4.8663 => 5) or multiply float numbers chosen power of 10 numbers become integers (4.8663 => 48663), might able use regexp query this.

i've indexed 3 documents integer numbers (5, 121 , 12) , i've been able retrieve 2 in 1-100 interval using following query.

{   "query": {     "regexp": {       "request": {         "value": "<1-100>"       }     }   } }

if absolutely need keep precision other reasons, might not work out you.
