I have two collections with the name "collection1" and "collection2" in database I had created 1 view with name "myview" for search document in both collection

I have the following document in both collections ->

{
    "name": "Mac",
    "age": 23,
    "contry":"India",
    "abc":true
  }

This aql query is working fine if {"abc" : false} in collection2 -> 

FOR doc IN myview search doc.abc == true update doc with {"alive":true} in collection1 LET updated = OLD RETURN updated

but in my case, this condition is (abc == true) true in both the collection so how can I do update single or multiple documents in multiple collection with single aql query

Not sure to understand what you want, but would this query fix your issue?

FOR doc IN myview 
    SEARCH doc.abc == true 
    UPDATE doc WITH {"alive":true} IN collection1 OPTIONS { ignoreErrors: true }
    UPDATE doc with {"alive":true} IN collection2 OPTIONS { ignoreErrors: true }
    LET updated = OLD 
    RETURN updated

OPTIONS { ignoreErrors: true } will make the query pass even if the document is not in the collection.

The query given by darkheir is working if we can do some changes like use of update operation for one by one for both collections like this

for collection 1 ->

 FOR doc IN myview 
        SEARCH doc.abc == true 
        UPDATE doc WITH {"alive":true} IN collection1 OPTIONS { ignoreErrors: true }
        LET updated = OLD 
        RETURN updated

and for Collection 2 ->

FOR doc IN myview 
    SEARCH doc.abc == true 
    UPDATE doc WITH {"alive":true} IN collection2 OPTIONS { ignoreErrors: true }
    LET updated = OLD 
    RETURN updated

how to query for both collection in single aql query
