incorrect handling of variables with special characters and multiple values

[Loori-R]

Hi! Thank you for feature. I tried this out and found some bugs.

Multi-value seems doesn't work. I have query:
consumer: $consumer
Choose 2 options and get nothing. From google devtools in network i see following query:
consumer: <null>|admin
I think it should have looked like this:
consumer: ("<null>" OR "admin")

Query works badly with values with special characters. I have query:
proxy_list: $proxy_list
From google devtools in network i see following query:
proxy_list: api_name:clientid-persons-v1;v1\\.14\\.1
I think it should have looked like this:
proxy_list: "api_name:clientid-persons-v1;v1.14.1"

I think need to add quotes and work through the moment with multi-value

multi value doesn't work yet as expected.
I would like to filter logs based on multiple selected values, of e.g. the host label

if using regexp filter host:~"$host" it partially works, but matches anything with thatsubstring. also, regexp filter is not good for performance

ideally the value could be passed to the multi exact :in() filter.

host:in($host) and compose_project:~"$compose_project" and $log_query

Workaround:
regexp filter with start ^ and end $ matcher in single quotes:

host:~'^$host$' and compose_project:~'^$compose_project$' and compose_service:~'^$compose_service$' and $log_query

also works in the variables section for filtering field_value results with query
