Hi

When i query zebra by control number option:

for example: http://sample.com/cgi-bin/koha/opac-search.pl?q=Control-number:187

It returns records which contain 187 in field 001 like 187 1877, 1870, 11875, ...

Is there any option to do an exact search on the whole subfield 001 to just return the whole word match?

"Control-number,ext:" not work. It returns  No results found for that in catalog
