Complex Search Ranking Algorithm

The ranking algorithm and index structure have gone through some major improvements since our intitial release of Zoom. The algorithm now produces more relevant results than previously before and also allow you greater control of your search results.

It achieves this by giving considering the position and location of the words found on the page, giving preference to words that are closer together, on the same page, etc.

Zoom Search Ranking Algorithm

Configurable weighting and boosting options

Control the importance of keywords depending on where they are found on a page (eg. title, meta description, meta keywords, headings, etc.). You can also boost entire pages, and specify preference based on content density and URL length.


This allows searches to match words which are similar or derivatives of each other. This addresses an often requested feature to match plural form of words to their singular forms. When this feature is enabled, a search for the word "boat" will match "boats" and "boating".

Screenshot of search results with stemming

Option to add pages and links to appear at the top of your results when a visitor searches for certain keywords or phrases. This allows you to specify the best results for certain searches, or gives you the ability to setup listings for your sponsors if you so desire.

Recommended links with Zoom V5, allows you to optionally associate links with keywords to appear at the top of your results

Custom Meta Fields

The Custom Meta Fields feature allows you to create a database-like search criteria for your website or online shop. This means you can have additional search fields like "Price", "Author", etc. for each item. It effectively means you can use Zoom to build simple custom databases with a multi-criteria search without actually having a database.
