Please read information below to find out how goods search is performed and what search settings can be done.

Trade provider

Trade provider is a service (or marketplace) for trading. Information about goods (titles, settings, configuration, etc.) and categories is sent to OT API from trade provider and then is broadcasted to website via OT API Key.

Check available trade providers.

Use GetProviderInfoList method to get list of available providers and information about them.

Own catalog

"Warehouse" provider will be added with additional Goods from Stock Module. You can use it to create your own catalog and add any goods (either from available providers or your own).

Search options and conditions

Each provider has its own set of search conditions. It can be varied depending on website goals. Use GetProviderSearchMethodInfoList method to get list of available search options and information what they support. 

Search can be done by two methods: SearchItemsFrame and BatchSearchItemsFrame. They are completely identical. Difference is that BatchSearchItemsFrame allows to get additional information right per one request besides search itself. Possible additional information will be described below. 

Search conditions are also identical. They are sent into xmlParameters and presented by structure SearchItemsParameters (this structure can be found, for example, in BatchSearchItemsFrame under "xmlParameters" field by clicking on "Structure"). It has xml format (like other structure parameters). xmlParameters is obligatory as it defines what we are looking for. Examples will be described below. 

What is called search conditions 

  • The main search criteria: search phrase, category, vendor, brand.
  • Additional search criteria: filters by characteristics, novelty of goods, and another different product’s parameters.
  • Sorting of search results.

From information about search methods you can get information what is available from these, and what variants are available. 

Getting information about search methods

In the following table you can see what can be known in information about search method and what search conditions it affects. For example, for search condition OrderBy (items sorting) can be found possible values from AvailableSorts field. In information about search method these parameters are in the table in one line. 

Comparison of search conditions and capabilities 

The following table provides a comparative description of search methods as they appear in parameters structure and how they are presented in search methods description.

Output modeOutputModeFull / TotalCount / Provider

Search results output mode.

Usual search with goods output and all related information is done. Other variants:

  • TotalCount — output of only total number of goods without information about goods.
    It is thus possible to get total number without wasting time for processing goods themselves.
  • Provider — output of only provider and search method without search itself. Provider and search method are defined on the basis of all search conditions and different settings.
CategoryModeNothing / External / InternalLeaf / CurrentLevel

Categories in search results output mode.

There is categories list (not always) besides goods in search results. These categories include found goods. They are usually called clarifying categories. There are several variants of processing and output:

  • Nothing — no categories output (if they are unnecessary)
  • External — output of external categories as they are without cast to internal
  • InternalLeaf — external categories cast to internal final categories (in any place of catalog)
  • CurrentLevel — external categories cast to internal categories of current level or to root categories (if search was not by category) or to those inside category (if search was by category). Thus, clarifying categories never go beyond current level of directory view.
Old conditionsIsTmalltrue/falseFeature of only Tmall goods choice.
