Regexp query for phrase

I need to search for two signature pattern with 'and' operator between two phrase. How to write the query for that. In these two phrase I as shown below the * means any number or value between 0-9 can be taken into consideration. How to write advance query for such type of pattern?
2 signature pattern- (GBUS error * timeout error) and​ (Asic * is not a valid chip)​

Easy way is use boolean query. You can use AND operation by must or filter clause.

Thanks for that. Will try boolean query but how to include the * condition as well which can take any value between 0-9?

There are regex query for regular expressions. If you are asking about the regular expression pattern, it seems you need to learn a little about regular expressions

GET 2021-0705-0486/_search
{
"query": {
"bool":{
"should":[
{"regexp": {"message.keyword": {
"value": ".GBUS error [0-9] timeout error.",
"flags": "ALL",
"case_insensitive": true,
"max_determinized_states": 10000,
"rewrite": "constant_score"}}
},
{"regexp": {"message.keyword": {
"value": ".Asic [0-9] is not a valid chip.",
"flags": "ALL",
"case_insensitive": true,
"max_determinized_states": 10000,
"rewrite": "constant_score"}}
}
]
}
}
}
This worked fine. Is this correct way to use regexp query for phrase with space along with bool query?

That looks ok and even better if it's working well.
What is the intention of "." on the start/end of pattern? To guarantee that pattern occurs truely inside the keyword?

From next time, please preformat your json with </> button. Thanks.

Sorry its typo. I used .* in start and end to search pattern inside the keyword.
Thanks for help.
