I've been dealing with a project. My goal is to get result from search engine in all circumstances for example, although i enter a keyword which is not include the keys inside data or is a empty string, I still need to get some result.How can i reach my goal?
you can see the query below :
query: {
regexp: {
title: "something to not found .*",
},
Try use "prefix" or "query_string"
You also can use title.keyword for exact value
1 -
{
"query": {
"prefix": {
"title": {
"value": "<data>"
}
}
}
}
2 -
{
"query": {
"query_string": {
"default_field": "title",
"query": "<data>*^0"
}
}
}
