This section allows the administrator to configure the front end search options, and the advanced search options. 
  At the top, this section lists all fields, representing category attributes. Next to each field, there is a Simple Search' checkbox, which includes this field in the simple search query. By default, only the Name' and the Description' fields are included. In general, it makes sense to include only the fields, which may contain text in them, otherwise when a visitor searches for a text keyword, the non-textual fields will be not searchable. Next there is a Weight' text box, in which the administrator can designate the importance of each field during a search. The fields with a larger weight will be more important then the fields with the lower weight. This is used when calculating the category relevance to the search keyword, for sorting of the results. The last column is the Advanced Search' check. It designated whether a particular field should be displayed on the Advanced Search' page, and should the visitors be able to search on it. By default, all fields are included. 
  Below the list of fields are the Category Relevance settings.
<ul> 
  <li> Increase importance if field contains a required keyword by  this specifies the percentage by which the weight of a field will increase, when a required keyword is found in that field. A required keyword is one that is preceded with a +' in the search key phrase. 
  <li> Search Relevance depends on _ % keyword  the percentage of relevance that comes from the keyword being found in that category. 
  <li> Search Relevance depends on _ % popularity - the percentage of relevance that is based on the category popularity. 
  <li> Search Relevance depends on _ % rating - the percentage of relevance that is based on the category rating.
</ul> 
  Below, the same forms repeat for user fields and for category custom fields, along with their respective relevance settings. Some of the search settings are not used in the current version  they are reserved for a future use.
