Suggesting spelling corrections and common word usage for end-user searches
Answer ID 2234   |   Last Review Date 03/18/2019

Can Oracle RightNow Cloud Service correct misspelled words when doing a search on the end-user pages?

Environment:

Search term feedback, Spell Check dictionary
Oracle B2C Service

Resolution:

Oracle RightNow Cloud Service can be configured to recommend a corrected spelling for an end-user who incorrectly enters a keyword while searching on the answer pages.  In addition, when this feature is enabled, if the end user searches on a common word that is excluded from searching, they receive a message:

"These words are very common and not included:"


Spelling evaluation:  When this spell correction feature is enabled, the actions below are executed.

  • The search initially looks through the 'dictionary' table to find the word the end-user typed. If the word can be found, then no suggestion will be given.
     
  • If the word is incorrectly spelled or not located in the dictionary, the system evaluates the dictionary files, including the userdic.tlx located in File Manager > dictionary files. 
     
  • The incorrectly spelled word is stemmed (stripped back to the base word) and alternative keywords are looked up in these files from the stemmed word.  
     
  • Finally, a new search is done using the new words found from the files above and a new search word is given through the Did you mean…? function.  


For example, if a user searches on the misspelled word "suppolt" instead of "support" , the search results for "suppolt" will display, but above that, the user will see the phrase:

"Did you mean: support"

The user can click on "support" and a new search is performed.

Another example, if a user searches on the misspelled word 'adress' instead of 'address' and there is not a 'Did you mean: address' suggestion, then it is likely that the wrong spelling of the word is used in an answer. The 'dictionary' table records this as a valid word.

In addition to spelling corrections, users are also told which common words are excluded from searching, namely words that are listed in the exclude_answers.txt file.


To enable the spell correction and common word feature:  You must enable the  EU_SEARCH_TERM_FEEDBACK_ENABLE configuration setting. This setting enables or disables the display of spelling corrections and word usage feedback on the end-user search page. By default, this setting is enabled.  The standard widget reports/ResultInfo must be included on the page and in the same <div> as the other search controls for best formatting.

When enabled, if someone searches the end-user pages and searches on a mistyped or misspelled word, a search suggestion that includes a corrected spelling is listed above the search results. The suggestion is a link so that the user can click the suggestion to view the search results for the corrected spelling.

Note:  This configuration setting is active for all end-user page sets.

Path to setting(s): Select Configuration from the navigation area > Site Configuration > Configuration Settings > and search by Key.
