I've recently found that when a user searches for a phrase in double quotes, the results page is highlighting individual words from within the phrase that may not actually match the full quoted phrase. This can make it difficult for the user to decide which document in the results list is the one they're looking for.
SharePoint 2007 does appear to be correctly filtering the results based on the complete phrase, it's just the highlighting that's off. For that matter, the text blurb that's shown in the results is also often not useful since it's based on the highlighted word.
Does anyone have any suggestions on how to fix this?
