If there are +** multiple entries in the b-tree with the same key (when only looking +** at the first pKeyInfo->nFields,) then default_rc can be set to -1 to +** cause the search to find the last match, or +1 to cause the search to +** find the first match. +** +** The key comparison functions will set eqSeen to true if they ever +** get and equal results when comparing this structure to a b-tree record. +** When default_rc!=0, the search might end up on the record immediately +** before the first match or immediately after the last match.
