What ranking weights are used when a facet is used to filter results
We are currently using facets for our Coveo search and wish to understand how the search results are ranked. If there are no keywords, title or description information, does Coveo rank by modified date?
For example, if we have three facets (blue, green, red) and when we select 'blue' and all items have been tagged with the color 'blue' and there are no keywords and 'blue' is not content and it not used in the title or description. How does Coveo rank the results? Modified Date??
When ranking documents, in addition to terms, many other factors are considered:
1. Document date
2. Query Ranking Expressions
3. Preferred Language set on the query parameters (for example, english documents if you set english as your preferred language)
4. Source reputation (it's a config setting on the source, inside CES configuration)
In your case, the document date and language must be the most influential factors, if you don't use any Query Ranking Expressions and have sources with equal reputation in the configuration.
