How to search for a product in the 1C-Bitrix catalog within one category?

Question

PHP

Good afternoon!
There is a form

<form action="/catalog/">
          <input type="text" class="bx_input_text" autocomplete="off" maxlength="300" size="300" value="" name="q" placeholder="Для оптимального подбора укажите наименование запчасти или её оригинальный номер" id="title-search-input">
          <input type="submit" class="bx_input_submit" value="" name="s">
</form>

it is necessary to search only in a certain category of the directory. There may be additional options, for example:

• Category ID to search
  
• Search category slug
  
• Category name to search
  

Please advise

Answer 1

section_id

Answer 2

your approach is not correct, you are using a form from the standard site search component, but you need to use the search for elements in the catalog
In the search component, specify 2 fields - section and name, make the section field hidden and static, you
also need to specify the filter name in both components.
