The current searching in labels is a bit minimal, and current only does keyword searching.

there is some old 2.2 code for more complete labels-searching, thats been commented out

ive logged a 'bug' for this - 2777

http://bugs.koha.org/cgi-bin/bugzilla/show_bug.cgi?id=2777

this fix...
  - enables the index-searching functionality
  - adds date-ranges
  - uses the numSearchResults syspref, not a hardcoded '20'
  - rewrote old 2.2 page-num code, (didnt work for 3.x)
  - some indent and whitepages tidys.
  - unused 2.2 search-code removed.
