elasticsearch combine multiple queries - elasticsearch

Question

I have an elasticsearch index for storing information about people.
To find specific persons I have some queries, each of them works alone but when I combine them using Bool Query I get an error.
One of the queries is a fuzzy search for the name
{
"query": {
"fuzzy_like_this": {
"fields": [
"firstname",
"lastname"
],
"like_text": "Peter"
}
}
}
Another query is for searching people who are born in a specific date range
{
"query": {
"range": {
"birthdate": {
"from": "1988-12-30",
"to": "1993-12-30"
}
}
}
}
Now I want to combine these two queries. My bool query:
{
"query": {
"bool": {
"must": [
{
"query": {
"fuzzy_like_this": {
"fields": [
"firstname",
"lastname"
],
"like_text": "Peter"
}
}
},
{
"query": {
"range": {
"birthdate": {
"from": "1988-12-30",
"to": "1993-12-30"
}
}
}
}
]
}
}
}
Although both queries work fine when I use them separately, when combining them I get an error.
There are people in my index whose firstname is Peter AND are born in this date range, but even if there were no people found I should get 0 results instead of an error.
The error says:
"error": "SearchPhaseExecutionException[Failed to execute phase [query], all shards failed;
nested: QueryParsingException[[indexname] No query registered for [query]]
Is combining queries the way I want to not possible with a bool query or did I just use the wrong syntax?

I think that you have a syntax error, the keyword query is not needed for queries that belong to must. In other words, it should be as follows:
{
"query": {
"bool": {
"must": [
{
"fuzzy_like_this": {
"fields": [
"firstname",
"lastname"
],
"like_text": "Peter"
}
},
{
"range": {
"birthdate": {
"from": "1988-12-30",
"to": "1993-12-30"
}
}
}
]
}
}
}
