[AIS] Typo Handling in AI Search is not auto correcting certain misspelled words and so the search does not return the expected results. It may work on one instance, but not on another instance.DescriptionAI Search replaces misspelled search query terms with auto-correction terms derived from indexed content. When deriving its list of auto-correction terms, the typo handling dictionary only considers indexed terms that satisfy the following conditions: The term includes at least 3 characters and no more than 255 characters.The term appears at least once in indexed records from the search profile's linked search source When a search query includes a term not present in the typo handling dictionary, AI Search looks for terms in the dictionary with similar spelling. If it finds a good match, it automatically replaces the original search query term with the dictionary term. For example, a search for emial, which isn't present on any indexed record, might auto-correct to the similarly spelled term email which exists on multiple indexed records and thus appears in the typo handling dictionary. The Search Results will return results based on the auto-corrected search query term, but also gives the user the option to search instead with the original search query term. However, if the misspelled word emial is present on any indexed record where the auto-correction terms are derived from, then it will not auto-correct, and it will return results based on the misspelled search query term emial, which may not return any results. CauseIf a misspelled word is present on any indexed record where the auto-correction terms are derived from, then it will not auto-correct the misspelled word, and it will return results based on the search query term that is misspelled.ResolutionYou need to remove the misspelled words on any indexed record where the auto-correction terms are derived from. The typo handling dictionary in table [ais_dictionary] linked to the Search Profile contains the Derive Settings and references the Indexed Sources which are used for the auto-correction terms from all the text fields, unless the field is specifically blocked in Blocked Fields or Blocked Terms. 1.
