Elasticsearch geo_distance in combination with other queries - elasticsearch

Question

Hello I have a problem with the combination of multiple queries within Elasticsearch.
The problem only occurs whenever I try to combine a multi_match query with the geo_distance query. The multi_match query works when the geo_distance query is not present and the geo_distance query works when the multi_match query is not present.
Whenever I execute the multi_match query without the geo_distance query I get the results that I expect. I also get the expected results when I try the geo_distance query without the multi_match query.
Boths results contain the dataset that I would expect to receive when both queries are executed together. But whenever I execute them together I receive 0 results.
When I combine the geo_distance query with a simple term query the search works. So I presume it is problem with the combination of queries.
I would appreciate any ideas.
My query is the following:
{
"query": {
"bool": {
"must": {
"bool": {
"should": {
"multi_match": {
"query": "CompanyName GmbH",
"fields": [
"originalName",
"legalName"
],
"type": "cross_fields",
"operator": "AND"
}
}
}
},
"filter": {
"bool": {
"should": {
"geo_distance": {
"location": [
9.87107,
51.69915
],
"distance": "30.0km",
"distance_type": "arc"
}
}
}
}
}
}
}
The mapping behind all of that is:
