elasticsearch - How do I index hierarchical data in elastic search? -

-

i have data similar file paths index in elasticsearch. (basically list of tokens separated delimiter)

ex data: a/b/c/d/e a/b/c/ a/m/n x/y/z

once index, should able query immediate children given token shown below.

for prefix of a, immediate children [b, m] prefix of x, immediate children [y] tokens @ root [a,x]

have considered parent-child relationship?

parent-child docs

indexed such you'd able query following

{   "query": {     "has_parent": {   } }  {   "query": {     "has_child": {   } }
