@ -79,8 +79,4 @@ against child documents such as `has_child` and `has_parent`.
There are a number of queries that fetch data via a get call during query parsing. For example the `terms` query when
using terms lookup, `template` query when using indexed scripts and `geo_shape` when using pre-indexed shapes. When these
queries are indexed by the `percolator` field type then the get call is executed once. So each time the `percolator`
query evaluates these queries, the fetches terms, shapes etc. as the were upon index time will be used.
The `wildcard` and `regexp` query natively use a lot of memory and because the percolator keeps the queries into memory
this can easily take up the available memory in the heap space. If possible try to use a `prefix` query or ngramming to
achieve the same result (with way less memory being used).
