+  },
+  city: {
+    type: FILTER_CONDITION_TYPE.MATCH_1_TO_1,
+    format: stringToRegexQuery
+  },
+  stateuf: {
+    type: FILTER_CONDITION_TYPE.MATCH_1_TO_1,
+    key: 'state.uf'
+  },
+  statename: {
+    type: FILTER_CONDITION_TYPE.MATCH_1_TO_1,
+    key: 'state.name'
+  },
+}
+```

+```
+const mapping = {
+  tags: {
+      type: FILTER_CONDITION_TYPE.CUSTOM_CONDITION,
+      format: tags => {
+        if (!tags) return []
+        return { tags: { $in: tags } };
+      },
+    },
+ };
