Is there a standard seach possibility to find closest docs to one reference doc by date criteria (if I don not know range yet)
Example dataset
```auto
index “person”
- doc : name=>Alice birthday=>01.01.1991
- doc : name=>Bobby birthday=>01.01.1963
- doc : name=>Karen birthday=>01.01.2006
- doc : name=>James birthday=>01.01.1998
- doc : name=>Chris birthday=>01.01.2000
- doc : name=>Diana birthday=>01.01.2022
- doc : name=>Wendy birthday=>01.01.1992
```
**Find closest to James** (2 precedent and 2 following from James' birthdate).
Result would be
```auto
1. Alice (91) -2
2. Wendy (93) -1
3. James (98) 0
4. Chris (00) 1
5. Karen (06) 2
```
Or a hint/example/direction how would you solve it.
