Spell Check Tab
Site Search > Relevance > Basic Relevance > Spell Check Tab
The Spell Check Tab of Site Search’s Basic Relevance screen lets us take a search keyword and apply a closeness algorithm to locate similar-looking words in the index (Data Driven) or in a custom list (Dictionary Driven).
When a query returns zero results, the Spell Check feature suggests an alternate spelling. The following image shows a spelling correction from the Relevance Preview screen.
Spellcheck may be Data Driven or it may be Dictionary Driven. If data-driven, Site Search maintains a Solr index of all the keywords that users have entered in their queries. When a query returns zero results, Site Search attempts to find a word that resembles the user’s current input.
If dictionary-driven, Site Search uses a spellcheck dictionary that you provide.
You can build the dictionary one word at a time, or you can upload a .CSV or .TXT file. Individual words should be separated by a comma or by whitespace (such as newline). When you upload a file, the new list completely replaces the old list.
