Knowledge search with dash does not return expected results
If you make a knowledge search with a sentence / search words that contains a dash rounded with spaces ( - ), like a - search, the result could be empty even if some answers exist
Reason:
The knowledge search uses Microsoft Full Text Search technology to retrieve information from the database.
A full-text search considers a word to be a string of characters without spaces or punctuation. The occurrence of a non-alphanumeric character can "break" a word during a search.
Using the dash ('-') in a search is not supported and may give unexpected results.
This is a limitation coming from Microsoft.
Workaround:
For the search with Dashes, suggestions are :
- Avoid using the dash in your search
- If you want to use dashes, you have to use double quote “” around the searched words.
