with "_search" you can search for specific index types. e.g. "workflow" index types:

display (?pretty)

with "?pretty" the content will be displaied in a structured way

http://172.17.2.91:9200/workflow/_search?pretty

amount of objects (&size)

if you wnat to see more than 10 objects ausgegeben use the option "size". "Size" defines the amount of ibjects to display e.g. 100

http://172.17.2.91:9200/workflow/_search?pretty&size=100

filter (&q=<feld>:<wert>)

IF you wnat to filter the objects you can use the function "&q=" e.g. filter attribute "status" for content "11":

http://172.17.2.91:9200/workflow/_search?pretty&size=100&q=status:11

If there are spaces in the filter expression use brackets:
