## This Script creates a Koha suggest and spellcheck database
|
||||
## for those features as visible on LibLime's opac: opac.liblime.com
|
||||
## It also contains the needed specs for creating a table of
|
||||
## queries for statistical purposes as well as a method of
|
||||
## returning popular searches via the suggest and spellcheck.
|
||||
## The code for running suggest and spellcheck can be found
|
||||
## either in Koha 2.4 CVS (HEAD as of this writing) or at
|
||||
## LibLime's website in the downlaods
|
||||
## section: http://liblime.com/c/downloads.html
