The Thesaurus search customization is helpful for your customers. It allows for misspellings in your store's search area without disrupting a search attempt. So if a customer is searching for cameras, but they type cameraas, the search will recognize and replace the misspelled word, allowing the search to continue uninterrupted.
Before you set up the Thesaurus search, you will need to allow it on your store. Go to Store > Store settings. Scroll down to "Allow Dictionary Search (Thesaurus):" and make sure it is checked.
In your store's admin console go to Global Settings > Search Customization > Thesaurus Search. If no groups are created click "new" in the top left.
When a search is made using the pretense for "all words," the Translate From words are translated to one term, the Root Word/Group Name.
Root Word/ Group Name: Correct term Translate From: Incorrect terms
On match "Any Word" searches, words in the Expand From list will be expanded to all terms in the Expand To list. Use a comma to separate multiple terms in the Translate From, Expand To and Expand From lists.
Expand To: Correct term, Correct term ( the search will return results for all terms) Expand From: Incorrect terms, Incorrect terms
