Number of devices to return with each call. Defaults to 100 and cannot return more. Passing a greater value is ignored. The response contains a `nextLink` property describing the URI path to get the next page of results if not all results could be returned at once.

By default all `meta` and `appInfo` properties are returned, this property is used to restrict the output to the desired properties. It also excludes all devices from the output that have none of the selected properties. In other terms, only devices having at least one of the selected property being set is part of the results. Examples: - `$select=appInfo` : select all devices having at least 1 appInfo, return them all and don’t return any meta property. - `$select=meta` : return only meta properties in the output. - `$select=appInfo,meta/firstSeen,meta/lastSeen` : return all `appInfo`, plus meta object containing only firstSeen and lastSeen properties. The format is thus a comma separated list of properties to select. Use `appInfo` to select all appInfo properties, `meta` to select all meta properties. Use `appInfo/{key}` and `meta/{key}` to select specific appInfo and meta properties.

Filter can be used to reduce the number of results. Filter is a boolean expression that can look like the following examples: * `$filter=deviceId gt 'abcdef0123456789abcdef0123456789'` * `$filter=lastModified le 1447284263690L` * `$filter=(deviceId ge 'abcdef0123456789abcdef0123456789') and (deviceId lt 'bacdef0123456789abcdef0123456789') and (lastModified gt 1447284263690L)` The first example is used automatically for paging when returning the `nextLink` property. The filter expression is a combination of checks on some properties that can be compared to their value. The available operators are: * `gt` : greater than * `ge` : greater than or equals * `lt` : less than * `le` : less than or equals * `and` : to add multiple checks (all checks must pass), optional parentheses can be used. The properties that can be used in the expression are the following: * `deviceId {operator} '{deviceIdValue}'` : a lexicographical comparison is made on the deviceId value, use single quotes for the value. * `lastModified {operator} {number}L` : returns only meta properties or appInfo properties whose last value modification timestamp compared to the specified value is matching (value is milliseconds since January 1st, 1970 UTC). Please note the `L` character after the number of milliseconds, its required when the number of milliseconds exceeds `2^31 - 1` (which is always the case for recent timestamps). Using `lastModified` excludes all devices from the output that have no property matching the timestamp criteria, like `$select`. Please note that the internal value of `lastModified` timestamp for a given property is never part of the results.
