Find line by text and delete from that line to other in bash

Using a linux bash or command line, i need to find certain string in a file and delete that line and the lines until white space.

My file:

geo_ws:
    resource: "@GeoWSBundle/Controller/"
    type:     annotation
    prefix:   /

mappublic:
    resource: "@MapPublicBundle/Controller/"
    type:     annotation
    prefix:   /map/ws

webpublic:
    resource: "@WebPublicBundle/Controller/"
    type:     annotation
    prefix:   /public

map:
    resource: "@MapBundle/Controller/"
    type:     annotation
    prefix:   /map

geo:
    resource: "@GeoBundle/Controller/"
    type:     annotation
    prefix:   /geo

ws:
    resource: "@WSBundle/Controller/"
    type:     annotation
    prefix:   /ws

web:
    resource: "@WebBundle/Controller/"
    type:     annotation
    prefix:   /

So i need to find i.e "map:", and clear all those 4 lines until next white line.

I've tried using seed, but i just can't figure it out.

An empty record separator indicates that records are delimited by blank lines:

$ awk -v RS='' -v ORS='\n\n' '!/^map/' file
geo_ws:
    resource: "@GeoWSBundle/Controller/"
    type:     annotation
    prefix:   /

webpublic:
    resource: "@WebPublicBundle/Controller/"
    type:     annotation
    prefix:   /public

geo:
    resource: "@GeoBundle/Controller/"
    type:     annotation
    prefix:   /geo

ws:
    resource: "@WSBundle/Controller/"
    type:     annotation
    prefix:   /ws

web:
    resource: "@WebBundle/Controller/"
    type:     annotation
    prefix:   /
