back-bdb

Hi
	The back-bdb/search.c:bdb_search(...) has a local variable called
ID candidates[...].
However, this array is filled only by two functions:
base_candidates(...) where only candidates[0] and [1] are filled,
search_candidates(...) where only [0], [1], [2] are filled. 
But the array is of size about 64K !!! Can anybody tell me why is this the
case, or is it that presently though only those few elements are used,
later (maybe when indices are implemented in back-bdb) the candidates
array shall hold much more elements (may be that candidates[...] shall
store all the elements from which one would search etc.) ?
Thank you
Debajyoti
