Ranking Factors allow users to re-rank the search based upon a variety of parameters. These parameters are called Ranking Factors. Depending on these settings, certain search results will be given higher priority than others based upon the parameters selected.
Each ranking factor can be given a certain amount of Importance, which is selected from the drop-down menu next to each factor, ranging from "off" to "max." The higher the importance, the higher rank in the results OU Search will give to pages that have "high scores" in that parameter.
The Rank Factors available are as follows:
- Word Ordering: Whether the words in the document are in the same order as they are in the search field. If set at "max," documents with the search terms in the same order as they appear in the search field will have a higher rank.
- Word Proximity: How close the words in the search field are to each other in the document. If set at "max," documents that have all the words in the search field grouped closely together will have a higher rank.
- Database Frequency: How frequently the search terms appear in the database table (usually the database table will consist of all the documents being searched in the site). If a search term appears more frequently in the database, its rank will decrease, because it is likely a more common term that will not lead users to the document they want. If set at "max," terms with a high amount of database frequency will see a large reduction in their ranking in the search results.
- Document Frequency: How frequently the search terms appear in the document. If set at "max," pages with the search terms appearing more frequently will have a higher rank.
- Position in Text: How close to the beginning of the document the search terms are found. If set at "max," pages with the search terms at the beginning of the document will have a higher rank.
- Depth in Site: How "deep" the document is in the site file structure. If set at "max," documents at or near the root of the site will be given priority.
