Bug 15468 - Search links on callnumbers with parentheses fails on OPAC results page

To Test:
1-before plugin search in opac for a call number with either a "(" or a ")" in it
2-it should come back with no results
3-use plugin
4-re-search the call number with "(" or ")"
5-the search should come back with results

It seems this only works with OPAC XSLT for results page turned off
and OPACItemsResultsDisplay turned on. - Then the callnumbers
in the result list will be linked for searching.
