### Filter logic
Supported logical matching:
* AND - all of the queries have to match
* OR - only one query has to match
* NOT - none of the queries have to match
### Explicit match
```
filter.NewQuery("Bool:true").Filter(&data)
filter.NewQuery("Bool:true", filter.OR).Filter(&data)
data = [{str1 42 true {s1 {1}}} {str2 42 true {s2 {2}}}]

### Wildcard match
