Hello everybody,
today I've tried to apply a filter on percolator's id something like this
```auto
GET index_test/type/75143/_percolate
{
"filter": {
"term": {
"_id": "percolator_29684"
}
}
}
```
but the response is
```auto
{
"took": 4,
"_shards": {
"total": 5,
"successful": 5,
"failed": 0
},
"total": 0,
"matches": []
}
```
If i put a term condition on another field is ok. Now is there another method to apply this constraint?
Thanks so much

There shouldn't be such a constraint, so this looks like a bug. What ES version are you using?
As a workaround you may want to try to percolate on the \_uid field instead:
```auto
GET /test/type/_percolate
{
"doc": {},
"filter": {
"term": {
"_uid": ".percolator#1"
}
}
}
```

Thank you so much for reply @mvg.
I've tried with your hint and it works. In dev I've 2.3.0v and in production I've 2.3.1v same error with filter on \_id it doesn't work.

@mvg I've tested with elasticsearch 2.3.3 and is the same situation. So is it a bug? However I open an issue on github

Thanks for checking! I think it is a bug too, so it makes sense to open a bug in Github.
