Script Filter
editScript Filter
editA filter allowing to define scripts as filters. For example:
"filtered" : { "query" : { ... }, "filter" : { "script" : { "script" : "doc['num1'].value > 1" } } }
Custom Parameters
editScripts are compiled and cached for faster execution. If the same script can be used, just with different parameters provider, it is preferable to use the ability to pass parameters to the script itself, for example:
"filtered" : { "query" : { ... }, "filter" : { "script" : { "script" : "doc['num1'].value > param1" "params" : { "param1" : 5 } } } }
Caching
editThe result of the filter is not cached by default. The _cache
can be
set to true
to cache the result of the filter. This is handy when
the same script and parameters are used on several (many) other queries.
Note, the process of caching the first execution is higher when caching
(since it needs to satisfy different queries).
