23/01/2018 : Matches documents that have fields matching a wildcard expression (not analyzed).
Supported wildcards are *, which matches any character sequence (including the empty one), and ?,
which matches any single character. Note this query can be slow, as it needs to iterate over many
terms. In order to prevent extremely slow wildcard queries, a wildcard term should not start with
one of the wildcards * or ?. In addition to the simple Query String we search directly in the
nested objects. This will additional return a inner_hits Object that contains the Id's for the
matched nested terms/objects.
new QueryWildcard()
.setTerm("searchField", "searchTermWildcard*", "NestedObjectName", "idOfMatchedNestedObject"))
.setIndex("foo")
.setType("FooBarDTO")
.setPageSize(10)
.setStartRecord(0)
.setExplain(false);
