There Seems to be a error in search in certain circumstances
I found a circumstance where searching for a chr record that exists in an index of Birmingham, england in 1808 does not get found when searching using the child's name. It does not find the record. But it finds the record only if searching using either parents names.
The record is in film 919767, index 7760346.
The chr record is for Eliza Sunderland, 1 aug 1808, parents john Sunderland and Mary.
This potentially is a serious flaw in the search engine, or there is a problem with this index.
