The Smart Search assigns a weight to each searchable field on your site. You can then adjust the importance of a match in each individual section to improve the relevancy of the results on your store. The sections are: Title Description Full Description Keywords SKU Variants Extra Fields If you site has a lot of unique highly customized data in the description field you will want to give this a higher weight. Likewise if you have a lot of redundant common information in the full description fields you can lower the relevancy of a match in this section. To tune your search. 1. Start with a query where you aren't happy with the order of the results. 2. Add &tune=npquery to the end of the URL. For example: /_search.php?page=1&q=search+query&tune=npquery 3. At the top of the page a list of productids and their matching score will be displayed. For example: Debug [0/0]: Array ( [69] => 10101 [5502] => 10102 [5503] => 10086 [5504] => 10032 [5501] => 10011 [5134] => 10011 [5132] => 10009 [5133] => 10006 [7592] => 987 [5131] => 877 4. Open the /modules/Smart_Search/smart_search_config.php file and find this section of code near line 60: $weight = array(); $weight['title'] = 5; // Title // $weight['descr'] = 1; // Short Description // $weight['fulldescr'] = 1; // Full Description // $weight['keywords'] = 3; $weight['sku'] = 1; $weight['variants'] = 2; $weight['extra_fields'] = 1; // Used only for the extra fields add-on // $weight['custom_fields'] = 1; // Used only for custom fields on the xcart_products table // A bit of trial and error will be needed, but as you adjust the weight of these fields you can then track the relevancy the Smart Search assigns to a product. For example. If a search for "red sweater" returns too many results on your site because the word "red" is found in a lot of keywords, lower the weight of the keywords field: $weight['keywords'] = 3; You can also increase the weight of fields to make others less relevant. In this case if the descr field is set to 1, and this can't be lowered. $weight['descr'] = 1; Setting the title to a higher number will also cause matches to the descr field to appear lower in the results. $weight['title'] = 100; The fields can be any integer above 0. For example: 1, 900, 9999999, 80, etc. | |
