A different result with filters

[Владислав Властовский]

Hi, I use 7.5.0 Solr

Why do I get two different results for similar requests?

First req/res:
{
  "query": "*:*",
  "limit": 0,
  "filter": [
    "{!parent which=kind_s:edition}condition_s:0",
    "{!parent which=kind_s:edition}price_i:[* TO 750000]"
  ]
}

{
  "response": {
    "numFound": 453,
    "start": 0,
    "docs": []
  }
}

And second query:
{
  "query": "*:*",
  "limit": 0,
  "filter": [
    "{!parent which=kind_s:edition}condition_s:0 AND price_i:[* TO 750000]"
  ]
}

{
  "response": {
    "numFound": 452,
    "start": 0,
    "docs": []
  }
}
