Using unaccent with SearchVector and SearchQuery in Django

Question

I have installed UnaccentExtension in Django but I\'m having problems using it with this search:

vector = SearchVector(\'title__unaccent\', \'abstract__unacc         


        

Answer 1

You can't use 'unaccent' in 'SearchVector' but you have to define a new "unaccented" config in PostgreSQL.

1. If you missed, installs the unaccent extension.

2. Create your unaccented dictionary in PostgrSQL or using an empty migrations with this SQL:

   CREATE TEXT SEARCH CONFIGURATION french_unaccent( COPY = french );
   ALTER TEXT SEARCH CONFIGURATION french_unaccent
   ALTER MAPPING FOR hword, hword_part, word
   WITH unaccent, french_stem;
   

3. Use this configuration in your Django query :

   SearchVector('title','abstract', config='french_unaccent')
   SearchQuery(word, config='french_unaccent')
   

You can find more info about this type of configuration in the official PostgreSQL documentation on in various articles
