Searchng through 4 index fields with different clauses

Elastic Stack Elasticsearch

Hi everyone. I have a question of using script for searching query phrasy through 4 index fields with several different cluases in script. Each script will have it's own clauses.

Script for searching through 4 fields:

PUT _scripts/liquid_instruments_search_date
{
"script": {
"lang": "mustache",
"source": {
"query": {
"bool": {
"must": [
{
"match": {
"isLiquidBoard": "true"
}
},
{
"match": {
"isDefaultUniversalExchange": "true"
}
},
{
"match":{
"isEnabled":"true"
}
},
{
"bool": {
"should": [
{
  "range": {
    "matDate": {
      "gte": "{{gte}}",
      "lte": "{{lte}}"
    }
  }
},
{
"bool": {
"must_not": [
{
"exists": {
"field": "matDate"
}
}
]
}
}
]
}
},
{
"bool": {
"should": [
{
"match": {
"ticker": {
"query": "{{query_string}}",
"fuzziness": 1,
"boost": 4
}
}
},
{
"match": {
"name": {
"query": "{{query_string}}",
"fuzziness": 1,
"boost": 3
}
}
},
{
"match": {
"assetSynonyms": {
"query": "{{query_string}}",
"fuzziness": 1,
"boost": 2
}
}
},
{
"match": {
"assetCode": {
"query": "{{query_string}}",
"fuzziness": 2,
"boost": 1
}
}
}
]
}
}
]
}
},
"from": "{{from}}{{^from}}0{{/from}}",
"size": "{{size}}{{^size}}10{{/size}}"
},
"params": {
"query_string": "query string"
}
}
}

Script for different clauses:

PUT _scripts/multipurpose_template
{
"script": {
  "lang": "mustache",
  "source": """{"sort": {{#toJson}}sort{{/toJson}},"from":"{{from}}","size":"{{size}}","query":{"bool":{"must":{{#toJson}}clauses{{/toJson}}}}}"""
}
}

How can I unite these two scripts above?
Example of data in index:
