# 47. Forespørgsel: Hent "ZonesMaps"

Forespørgsel for at få brugernes "ZonesMaps". For at implementere pagineringslogik, brug forespørgselsparameteren `sideStørrelse`. Filteret fungerer som en OG-betingelse, f.eks. muligt at filtrere efter `farmUuid`, `fieldUuid`, `vectorAnalysisMapUuid`, `etiketter`, `formål`, `type`, og `kunMedSatser` i den ene forespørgsel eller bruge kun én filterbetingelse eller ikke bruge nogen betingelse. 

Begrænsninger: filtrering efter `formål`, `type`, og `kunMedSatser` virker kun i forbindelse med `fieldUuid`. Det er tilladt at søge zoneskort efter `vectorAnalysisMapUuid` enkelt attribut. 

Der er `sidstEvalueretNøgle` og `samletAntal`  i svaret.  `sidstEvalueretNøgle` refererer til den sidst behandlede post, der matcher filterbetingelserne.  `samletAntal` - er det samlede antal poster, der matcher filterbetingelserne.
