====== Stop Words and Synonyms ======

VuFind's Solr index allows the library to configure their own custom stop words list as well as a list of synonyms used in searching.  There is a default stop words list as well as a few basic synonyms that come prepackaged with VuFind - however it is very easy to change these to customize for your library's needs.

===== Stop Words =====

Edit the file: [[https://github.com/vufind-org/vufind/blob/dev/solr/vufind/biblio/conf/stopwords.txt|stopwords.txt]] and simply remove or add new words to the list.

===== Synonyms =====

Edit the file: [[https://github.com/vufind-org/vufind/blob/dev/solr/vufind/biblio/conf/synonyms.txt|synonyms.txt]] and simply follow the examples provided to create new synonyms.
VuFind's default synonyms are for the numbers 1 - 5.  It lists synonyms for the following:
  * 1,i,I,one,One
  * 2,ii,II,two,Two
  * 3,iii,III,three,Three
  * 4,iv,IV,four,Four
  * 5,v,V,five,Five
This allows a user to search for "world war two" and find items with the term "world war ii"

===== Important Note =====

Remember to [[administration:starting_and_stopping_solr#restarting_solr_manually|restart Solr]] after changing either of these files.  When you change your stopword settings, it is also necessary to reindex all of your records.
