MultiIndex filter and search

[samdash (Sam)]

Hi ,

I have 2 indexes com and article , which contain documents which are different and only thing that is common between the documents is _id , i need a filter and search Query from these 2 indexes , please let me know how to approach on this . First i need to Filter on COM index by TAGID and do search "text" from articleIndex
Filter by TAGID will return me _id ABC1234 and search for "Airtel iPhone" should return the same document however when i search for " something not in the document" it should not return ABC1234 article , please let me know how to go about this.

com index has following documents

{
  "_index": "com",
  "_type": "com",
  "_id": "ABC1234",
   "_score": 1,
    "locale": "en_US",
    "tags": [
      {
        "tagid": "TAG_A"
       },
      {
        "tagid": "TAG_B"
       }
    ]
  }
}

{
  "_index": "article",
  "_type": "article",
  "_id": "ABC1234",
  "_version": 1,
  "_score": 1,
