How to search using boolean operators AND, OR or Not in dev tools?

Elastic Stack Elasticsearch

Hello @dadoonet,

I have tried below query:

POST /multipletable/_search
{
"query":{
"bool":{
"must":[ {
"match":{
"title":{
"query":"test"} } },
{
"match":{
"contentid":{
"query":"4016768"} } }
]
}
}
}

in above query, i have mentioned in which field i have to search, like search for test in title field AND search for 4016768 in contentid.
i dont want to use field name but have to perform boolean search in below format query:

GET new_database,new_attachment/_search?size=10000
{
"query": {
"multi_match": {
"query": "4245489",
"fields": ["contentid^5", "title^4","object_summary^3","content^2","submitted_for_name"] }
}
}

Regards,
Priyanka
