3. The Metaweb Query Language: Limit and offset

You use cursors. Ask for cursor:null in your first query. It will come back with a token filled in; pass that back to get the next set of results and a new cursor.

I figured enough that you can use "limit" reserved to get the first few results of a query,

say for some query

"limit" : 5

this fetches the first five ,

how do I fetch the next 5

3. The Metaweb Query Language: Howto forbid a property from existing

2008-06-12T22:09:49.0005Z

something which is not documented here is that "optional" : "forbidden" can be used to require that nothing like that object exist.

Good morning all.

Has a random feature become manifest in the meantime or is is on the agenda?

3. The Metaweb Query Language: MQL query for instance count

2008-06-02T16:46:43.0007Z

No problem! One thing though... the query may time out on types with a large number of instances.

Thanks a lot cheunger. That was of great help.

{

"type" : "/type/type_name",

"return" : "count"

}

I tried to find the documentation for this, but I wasn't able to. We're in the process of cleaning up the documenation, and I am sure will be included.

Helo,

I am trying to write an MQL to count the number of instances of a given type but not being able to figure out. Can anyone help please?

Currently there is no way to have MQL return a random set of items. You might want to post this as an enhancement request here.

is there any way to retrieve a random item in list of items? I often run into scenarios where i want to test a random series of (valid) us addresses against my business rules. it would be great if i could so something like this:

{

  "query" : [
    {
      "citytown" : null,
      "limit" : 10,
      "sort" : random,
      "state_province_region" : null,
      "street_address" : null,
      "type" : "/location/mailing_address"
    }
  ]

3. The Metaweb Query Language: requesting lists with minimum counts

2008-01-16T23:52:17.0007Z

Good question - currently, MQL supports constraints on number and datetime properties, but not properties where the expected type is something other than that. I'll pass your request on to the MQL team.

2008-01-16T20:47:48.0012Z

Is there any way to require a number of items in a list? For example, query for all movie actors with 20+ films to their name?

3. The Metaweb Query Language: 3.2.3 Suggested Correction

2007-10-13T00:03:21.0007Z

You are correct that this section is incorrect. We need to correct that. Two issues:

1) the syntax for guids in the ID field just changed to /guid/9202a8c04000641f800000000006df1b
2) if there's a human-readable ID for a topic, that we will be returned rather than the guid, so as you pointed out: /topic/en/the_police.

3. The Metaweb Query Language: 3.2.3 Suggested Correction

2007-10-12T01:44:02.0012Z

In section 3.2.3, and example is given on how to get the ID of an object, more specifically, its guid. However, following along with the example, the online query editor actually returns the full-qualified name (right?), for example: "topic/en/the_police."
