# 47. Query: Get "ZonesMaps"

Query to get user "ZonesMaps". To implement pagination logic, use the query parameter `pageSize`. The filter works like AND condition, e.g. possible to filter by `farmUuid`, `fieldUuid`, `vectorAnalysisMapUuid`, `labels`, `purpose`, `type`, and `withRatesOnly` in the one query or use just one filter condition or use no condition. 

Restrictions: filtering by `purpose`, `type`, and `withRatesOnly` works only in conjunction with `fieldUuid`. It is allowed to search zones maps by `vectorAnalysisMapUuid` single attribute. 

There are `lastEvaluatedKey` and `totalCount`  in response. The `lastEvaluatedKey` refers to the last processed record to match filter conditions. The `totalCount` - is the total number of records that match the filtering conditions.

  getZonesMaps(
    filter: {
      pageSize: 10
      fieldUuid: "<placeholder_of_field_uuid>"
