Words used in a SQL full-text search are highlighted in the results displayed in the clients and in the Web interface - in the same way as when using Exalead.
There are some limitations though: Exalead returns a complete list of words to highlight, so if a search for 'fernandez' matches both 'Fernandez' and 'Fernández' then both words are returned by Exalead, and they will both be highlighted in the result.
When using SQL full-text the list of words to highlight is simply extracted from the query, so in the example above only 'Fernandez' will be highlighted.
