The Catalog Search seems to be returning irrelevant search results probably because it is searching also based on descriptions. What are the proper CATALOG SEARCH settings? Also - layered navigation seems to be connected with this somehow - what is layered navigation and how do I know if I have it or not?
I too faced the same problem before. This is because by default "description" attribute is set to Searchable.
- Login to Magento Admin Panel.
- Goto Catalog > Attributes > Manage Attributes
- Search for "description" attribute and edit it.
- Change Searchable field to NO
- Save it.
- ReIndex data.
- Clear Cache if required.
This should work. =)
