Add "equal" option to the title search "Authority id" index
When searching for titles by authority ID, currently the search supports searching with: Contains keywords, contains phrase, is empty, not contains keywords, not contains phrase, is not empty.
Add the option to also search by "equals".

The "Authority id" index is meant to create a recall with the highest degree of precision. However, without the option "equals" it does not.
Currently one receives BIB records linked to an authority record with the ID one searched for, but also BIB records linked to other authority records with IDs consisting of the string one searched for and any number of additional digits, e.g. searching for ID "123456" also shows BIB records linked to authority records with numbers "12345678", "(DE-588)123456", "(NO-TrBIB)123456" etc.
It would be great, if this enhancement could be implemented, to boost precision of queries.
